```
public class JDBCPreparedStatement
extends java.lang.Object
implements java.sql.PreparedStatement
```
An object that represents a precompiled SQL statement.
A SQL statement is precompiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.
Note: The setter methods (setShort, setString, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type INTEGER, then the method setInt should be used.
If arbitrary parameter type conversions are required, the method setObject should be used with a target SQL type.
In the following example of setting a parameter, con represents an active connection:
```
   BigDecimal sal = new BigDecimal("153833.00");
   PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
                                     SET SALARY = ? WHERE ID = ?");
   pstmt.setBigDecimal(1, sal);
   pstmt.setInt(2, 110592);
 
```
HSQLDB-Specific Information:
From version 2.0, the implementation meets the JDBC specification requirement that any existing ResultSet is closed when execute() or executeQuery() methods are called. The connection property close_result=true is required for this behaviour.
JDBCPreparedStatement objects are backed by a true compiled parametric representation. Hence, there are now significant performance gains to be had by using a JDBCPreparedStatement object in preference to a JDBCStatement object when a short-running SQL statement is to be executed more than once.
When it can be otherwise avoided, it should be considered poor practice to fully prepare (construct), parameterize, execute, fetch and close a JDBCParameterMetaData object for each execution cycle. Indeed, because the prepare and execute phases both represent a round-trip to the engine, this practice is likely to be noticeably less performant for short-running statements (and possibly even orders of magnitude less performant over network connections for short-running statements) than the equivalent process using JDBCStatement objects, albeit far more convenient, less error prone and certainly much less resource-intensive, especially when large binary and character values are involved, due to the optimized parameterization facility.
Instead, when developing an application that is not totally oriented toward the execution of ad hoc SQL, it is recommended to expend some effort toward identifying the SQL statements that are good candidates for regular reuse and adapting the structure of the application accordingly. Often, this is done by recording the text of candidate SQL statements in an application resource object (which has the nice side-benefit of isolating and hiding differences in SQL dialects across different drivers) and caching for possible reuse the PreparedStatement objects derived from the recorded text.
Starting with 2.0, when built under a JDBC 4 environment, statement caching can be transparently enabled or disabled on a statement-by-statement basis by invoking setPoolable(true | false), respectively, upon Statement objects of interest.
Multi thread use:
A PreparedStatement object is stateful and should not normally be shared by multiple threads. If it has to be shared, the calls to set the parameters, calls to add batch statements, the execute call and any post-execute calls should be made within a block synchronized on the PreparedStatement Object.

    x - the parameter value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
  - setString
```
public void setString(int parameterIndex,
                      java.lang.String x)
               throws java.sql.SQLException
```
    Sets the designated parameter to the given Java String value. The driver converts this to an SQL VARCHAR or LONGVARCHAR value (depending on the argument's size relative to the driver's limits on VARCHAR values) when it sends it to the database.
    
    HSQLDB-Specific Information:
    Including 2.0, HSQLDB represents all XXXCHAR values internally as java.lang.String objects; there is no appreciable difference between CHAR, VARCHAR and LONGVARCHAR.
    
    Specified by:
    
    setString in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the parameter value

  - setBytes
```
public void setBytes(int parameterIndex,
                     byte[] x)
              throws java.sql.SQLException
```
    Sets the designated parameter to the given Java array of bytes. The driver converts this to an SQL VARBINARY or LONGVARBINARY (depending on the argument's size relative to the driver's limits on VARBINARY values) when it sends it to the database.
    
    HSQLDB-Specific Information:
    Including 2.0, HSQLDB represents all XXXBINARY values the same way internally; there is no appreciable difference between BINARY, VARBINARY and LONGVARBINARY as far as JDBC is concerned.
    
    Specified by:
    
    setBytes in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...

             throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Date value using the default time zone of the virtual machine that is running the application. The driver converts this to an SQL DATE value when it sends it to the database.
    
    HSQLDB-Specific Information:
    When a setXXX method is used to set a parameter of type TIMESTAMP WITH TIME ZONE or TIME WITH TIME ZONE the time zone of the client application is used as time zone
    
    Specified by:
    
    setDate in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the parameter value

  - setTime
```
public void setTime(int parameterIndex,
                    java.sql.Time x)
             throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Time value. The driver converts this to an SQL TIME value when it sends it to the database.
    
    HSQLDB-Specific Information:
    When a setXXX method is used to set a parameter of type TIMESTAMP WITH TIME ZONE or TIME WITH TIME ZONE the time zone of the client application is used as time zone

    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the parameter value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
  - setTimestamp
```
public void setTimestamp(int parameterIndex,
                         java.sql.Timestamp x)
                  throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Timestamp value. The driver converts this to an SQL TIMESTAMP value when it sends it to the database.
    
    HSQLDB-Specific Information:
    When a setXXX method is used to set a parameter of type TIMESTAMP WITH TIME ZONE or TIME WITH TIME ZONE the time zone of the client application is used as time zone.
    When this method is used to set a parameter of type TIME or TIME WITH TIME ZONE, then the nanosecond value of the Timestamp object will be used if the TIME parameter accepts fractional seconds.
    
    Specified by:
    
    setTimestamp in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the parameter value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
  - setAsciiStream
```
public void setAsciiStream(int parameterIndex,
                           java.io.InputStream x,
                           int length)
                    throws java.sql.SQLException
```
    Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.
    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
    
    HSQLDB-Specific Information:
    From HSQLDB 2.0 this method uses the US-ASCII character encoding to convert bytes from the stream into the characters of a String.
    This method does not use streaming to send the data, whether the target is a CLOB or other binary object.
    For long streams (larger than a few megabytes) with CLOB targets, it is more efficient to use a version of setCharacterStream which takes the a length parameter.
    
    Specified by:
    
    setAsciiStream in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the Java input stream that contains the ASCII parameter value
    
    length - the number of bytes in the stream
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
  - setUnicodeStream
```
@Deprecated
public void setUnicodeStream(int parameterIndex,
                             java.io.InputStream x,

                      throws java.sql.SQLException
```
    Deprecated.
    Use setCharacterStream
    
    Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format. The byte format of the Unicode stream must be a Java UTF-8, as defined in the Java Virtual Machine Specification.
    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
    
    HSQLDB-Specific Information:
    Starting with 2.0, this method behaves according to the JDBC4 specification (the stream is treated as though it has UTF-8 encoding. This method is deprecated: please use setCharacterStream(...) instead.
    
    Specified by:
    
    setUnicodeStream in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - a java.io.InputStream object that contains the Unicode parameter value
    
    length - the number of bytes in the stream
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - setBinaryStream

                            int length)
                     throws java.sql.SQLException
```
    Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.
    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
    
    HSQLDB-Specific Information:
    Since 1.7.2, this method works according to the standard.
    
    Specified by:
    
    setBinaryStream in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the java input stream which contains the binary parameter value
    
    length - the number of bytes in the stream
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
  - clearParameters
```
public void clearParameters()
                     throws java.sql.SQLException
```
    Clears the current parameter values immediately.
    In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters.
    
    Specified by:
    
    clearParameters in interface java.sql.PreparedStatement
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed PreparedStatement
  - setObject
```
public void setObject(int parameterIndex,
                      java.lang.Object x,
                      int targetSqlType)
               throws java.sql.SQLException
```
    Sets the value of the designated parameter with the given object. This method is similar to setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength), except that it assumes a scale of zero.
    
    HSQLDB-Specific Information:
    Since 1.7.2, this method supports conversions listed in the conversion table B-5 of the JDBC 3 specification.
    
    Specified by:
    
    setObject in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the object containing the input parameter value
    
    targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support the specified targetSqlType

  - setObject
```
public void setObject(int parameterIndex,
                      java.lang.Object x)
               throws java.sql.SQLException
```
    Sets the value of the designated parameter using the given object.
    The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.
    Note that this method may be used to pass database- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, RowId, SQLXML or Array, the driver should pass it to the database as a value of the corresponding SQL type.
    Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the setNull or the setObject(int parameterIndex, Object x, int sqlType) method should be used instead of setObject(int parameterIndex, Object x).
    Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.
    
    HSQLDB-Specific Information:
    Since 1.7.2, this method supports conversions listed in the conversion table B-5 of the JDBC 3 specification.
    
    Specified by:
    
    setObject in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the object containing the input parameter value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or the type of the given object is ambiguous
  - execute
```
public boolean execute()
                throws java.sql.SQLException
```
    Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate.
    The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).
    
    HSQLDB-Specific Information:
    If the statement is a call to a PROCEDURE, it may return multiple fetchable results.
    
    Specified by:
    
    execute in interface java.sql.PreparedStatement
    
    Returns:
    
    true if the first result is a ResultSet object; false if the first result is an update count or there is no result
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed PreparedStatement or an argument is supplied to this method
    
    java.sql.SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement

  - addBatch
```
public void addBatch()
              throws java.sql.SQLException
```
    Adds a set of parameters to this PreparedStatement object's batch of commands.
    
    HSQLDB-Specific Information:
    Since 1.7.2, this feature is supported.
    
    Specified by:
    
    addBatch in interface java.sql.PreparedStatement
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed PreparedStatement

                               int length)
                        throws java.sql.SQLException
```
    Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.
    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
    
    HSQLDB-Specific Information:
    From HSQLDB 2.0 this method uses streaming to send data when the target is a CLOB.
    HSQLDB represents CHARACTER and related SQL types as UTF16 Unicode internally, so this method does not perform any conversion.
    
    Specified by:
    
    setCharacterStream in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    reader - the java.io.Reader object that contains the Unicode data
    
    length - the number of characters in the stream
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
    
    Since:

```
public void setRef(int parameterIndex,
                   java.sql.Ref x)
            throws java.sql.SQLException
```
    Sets the designated parameter to the given REF(<structured-type>) value. The driver converts this to an SQL REF value when it sends it to the database.
    
    HSQLDB-Specific Information:
    Including 2.0 HSQLDB does not support the SQL REF type. Calling this method throws an exception.
    
    Specified by:
    
    setRef in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - an SQL REF value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method

```
public void setBlob(int parameterIndex,
                    java.sql.Blob x)
             throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Blob object. The driver converts this to an SQL BLOB value when it sends it to the database.
    
    HSQLDB-Specific Information:
    For parameters of type Blob, setBlob works normally.
    In addition since 1.7.2, setBlob is supported for BINARY and VARBINARY parameters. In this context, the Blob object is hard-limited to those of length less than or equal to Integer.MAX_VALUE. In practice, soft limits such as available heap and maximum disk usage per file (such as the transaction log) dictate a much smaller maximum length.
    For BINARY and VARBINARY parameter types setBlob(i,x) is roughly equivalent (null and length handling not shown) to:
    setBinaryStream(i, x.getBinaryStream(), (int) x.length());
    Specified by:
    
    setBlob in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - a Blob object that maps an SQL BLOB value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement

public void setClob(int parameterIndex,
                    java.sql.Clob x)
             throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Clob object. The driver converts this to an SQL CLOB value when it sends it to the database.
    
    HSQLDB-Specific Information:
    For parameters of type Clob, setClob works normally.
    In addition since 1.7.2, setClob is supported for CHARACTER and VARCHAR parameters. In this context, the Clob object is hard-limited to those of length less than or equal to Integer.MAX_VALUE. In practice, soft limits such as available heap and maximum disk usage per file (such as the transaction log) dictate a much smaller maximum length.
    For CHARACTER and VARCHAR parameter types setClob(i,x) is roughly equivalent (null and length handling not shown) to:
    setCharacterStream(i, x.getCharacterStream(), (int) x.length());
    Specified by:
    
    setClob in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - a Clob object that maps an SQL CLOB value
    
    Throws:

public void setArray(int parameterIndex,
                     java.sql.Array x)
              throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Array object. The driver converts this to an SQL ARRAY value when it sends it to the database.
    
    HSQLDB-Specific Information:
    From version 2.0, HSQLDB supports the SQL ARRAY type.
    
    Specified by:
    
    setArray in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - an Array object that maps an SQL ARRAY value
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement

```
public java.sql.ResultSetMetaData getMetaData()
                                       throws java.sql.SQLException
```
    Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.
    Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.
    NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.
    
    HSQLDB-Specific Information:
    Since 1.7.2, this feature is supported and is inexpensive as it is backed by underlying DBMS support. If the statement generates an update count, then null is returned.
    
    Specified by:
    
    getMetaData in interface java.sql.PreparedStatement
    
    Returns:
    
    the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed PreparedStatement
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method

                    java.util.Calendar cal)
             throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
    
    Specified by:
    
    setDate in interface java.sql.PreparedStatement
    
    Parameters:

             throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
    
    HSQLDB-Specific Information:
    When a setXXX method is used to set a parameter of type TIMESTAMP WITH TIME ZONE or TIME WITH TIME ZONE the time zone (including Daylight Saving Time) of the Calendar is used as time zone for the value.
    
    Specified by:

                         java.util.Calendar cal)
                  throws java.sql.SQLException
```
    Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
    
    HSQLDB-Specific Information:
    When a setXXX method is used to set a parameter of type TIMESTAMP WITH TIME ZONE or TIME WITH TIME ZONE the time zone (including Daylight Saving Time) of the Calendar is used as time zone.
    In this case, if the Calendar argument is null, then the default Calendar for the clients JVM is used as the Calendar
    When this method is used to set a parameter of type TIME or TIME WITH TIME ZONE, then the nanosecond value of the Timestamp object is used if the TIME parameter accepts fractional seconds.
    
    Specified by:
    
    setTimestamp in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the parameter value
    
    cal - the Calendar object the driver will use to construct the timestamp

                    java.lang.String typeName)
             throws java.sql.SQLException
```
    Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.
    Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
    
    HSQLDB-Specific Information:
    HSQLDB simply ignores the sqlType and typeName arguments.
    
    Specified by:
    
    setNull in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    sqlType - a value from java.sql.Types
    
    typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
    
    java.sql.SQLFeatureNotSupportedException - if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type or if the JDBC driver does not support this method

  - executeBatch
```
public int[] executeBatch()
                   throws java.sql.SQLException
```
    Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:
    
    A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
    A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown
    If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
    A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails
    
    A driver is not required to implement this method. The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to process commands in a batch update after a BatchUpdateException object has been thrown.
    
    HSQLDB-Specific Information:
    Starting with HSQLDB 1.7.2, this feature is supported.
    HSQLDB stops execution of commands in a batch when one of the commands results in an exception. The size of the returned array equals the number of commands that were executed successfully.
    Specified by:
    
    executeBatch in interface java.sql.Statement
    
    Returns:
    
    an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs, this method is called on a closed Statement or the driver does not support batch statements. Throws BatchUpdateException (a subclass of SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.

```
    Retrieves any auto-generated keys created as a result of executing this Statement object. If this Statement object did not generate any keys, an empty ResultSet object is returned.
    Note:If the columns which represent the auto-generated keys were not specified, the JDBC driver implementation will determine the columns which best represent the auto-generated keys.
    
    HSQLDB-Specific Information:
    Starting with version 2.0, HSQLDB supports this feature with single-row and multi-row insert, update and merge statements.
    This method returns a result set only if the executeUpdate methods that was used is one of the three methods that have the extra parameter indicating return of generated keys
    If the executeUpdate method did not specify the columns which represent the auto-generated keys the IDENTITY column or GENERATED column(s) of the table are returned.
    The executeUpdate methods with column indexes or column names return the post-insert or post-update values of the specified columns, whether the columns are generated or not. This allows values that have been modified by execution of triggers to be returned.
    If column names or indexes provided by the user in the executeUpdate() method calls do not correspond to table columns (incorrect names or indexes larger than the column count), an empty result is returned.
    
    Specified by:

    Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB

```
    Sets the designated parameter to a InputStream object. The Inputstream must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setBinaryStream (int, InputStream, int) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB
    
    HSQLDB-Specific Information:
    In HSQLDB 2.0, this method uses streaming to send the data when the stream is assigned to a BLOB target. For other binary targets the stream is read on the client side and a byte array is sent.
    
    Specified by:

    Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB

                      int scaleOrLength)
               throws java.sql.SQLException
```
    Sets the value of the designated parameter with the given object. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.
    The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.
    Note that this method may be used to pass database-specific abstract data types.
    
    Specified by:
    
    setObject in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the object containing the input parameter value
    
    targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
    
    scaleOrLength - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero

                    throws java.sql.SQLException
```
    Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.
    Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
    
    HSQLDB-Specific Information:
    From HSQLDB 2.0 this method uses the US-ASCII character encoding to convert bytes from the stream into the characters of a String.
    This method does not use streaming to send the data, whether the target is a CLOB or other binary object.
    For long streams (larger than a few megabytes) with CLOB targets, it is more efficient to use a version of setCharacterStream which takes the a length parameter.

These types all have an absolute maximum element upper bound determined by the Java array index limit java.lang.Integer.MAX_VALUE. For XXXBINARY types, this translates to Integer.MAX_VALUE bytes. For XXXCHAR types, this translates to 2 * Integer.MAX_VALUE bytes (2 bytes / character).
    In practice, field sizes are limited to values much smaller than the absolute maximum element upper bound, in particular due to limits imposed on the maximum available Java heap memory.
    
    Specified by:
    
    setMaxFieldSize in interface java.sql.Statement
    
    Parameters:
    
    max - the new column size limit in bytes; zero means there is no limit
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs, this method is called on a closed Statement or the condition max >= 0 is not satisfied

  - getQueryTimeout
```
public int getQueryTimeout()
                    throws java.sql.SQLException
```
    Retrieves the number of seconds the driver will wait for a Statement object to execute. If the limit is exceeded, a SQLException is thrown.
    
    HSQLDB-Specific Information:
    To present, HSQLDB always returns zero, meaning there is no limit.
    
    Specified by:
    
    getQueryTimeout in interface java.sql.Statement
    
    Returns:
    
    the current query timeout limit in seconds; zero means there is no limit

  - setQueryTimeout
```
public void setQueryTimeout(int seconds)
                     throws java.sql.SQLException
```
    Sets the number of seconds the driver will wait for a Statement object to execute to the given number of seconds. If the limit is exceeded, an SQLException is thrown. A JDBC driver must apply this limit to the execute, executeQuery and executeUpdate methods. JDBC driver implementations may also apply this limit to ResultSet methods (consult your driver vendor documentation for details).
    
    HSQLDB-Specific Information:
    The maximum number of seconds to wait is 32767.
    
    Specified by:
    
    setQueryTimeout in interface java.sql.Statement
    
    Parameters:
    
    seconds - the new query timeout limit in seconds; zero means there is no limit
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs, this method is called on a closed Statement or the condition seconds >= 0 is not satisfied
    
    See Also:

  - cancel
```
public void cancel()
            throws java.sql.SQLException
```
    Cancels this Statement object if both the DBMS and driver support aborting an SQL statement. This method can be used by one thread to cancel a statement that is being executed by another thread.
    
    HSQLDB-Specific Information:
    HSQLDB version 2.3.4 and later supports aborting an SQL query or data update statement.
    
    Specified by:
    
    cancel in interface java.sql.Statement
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed Statement
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - getWarnings
```
public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
```
    Retrieves the first warning reported by calls on this Statement object. Subsequent Statement object warnings will be chained to this SQLWarning object.
    The warning chain is automatically cleared each time a statement is (re)executed. This method may not be called on a closed Statement object; doing so will cause an SQLException to be thrown.
    Note: If you are processing a ResultSet object, any warnings associated with reads on that ResultSet object will be chained on it rather than on the Statement object that produced it.
    
    HSQLDB-Specific Information:
    From 1.9 HSQLDB, produces Statement warnings.
    
    Specified by:
    
    getWarnings in interface java.sql.Statement
    
    Returns:
    
    the first SQLWarning object or null if there are no warnings
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed Statement
  - clearWarnings
```
public void clearWarnings()
                   throws java.sql.SQLException
```
    Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement object.
    
    HSQLDB-Specific Information:
    Supported in HSQLDB 1.9.
    
    Specified by:
    
    clearWarnings in interface java.sql.Statement
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed Statement
  - setCursorName
```
public void setCursorName(java.lang.String name)
                   throws java.sql.SQLException
```
    Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods. This name can then be used in SQL positioned update or delete statements to identify the current row in the ResultSet object generated by this statement. If the database does not support positioned update/delete, this method is a noop. To ensure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should have the form SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may fail.
    Note: By definition, the execution of positioned updates and deletes must be done by a different Statement object than the one that generated the ResultSet object being used for positioning. Also, cursor names must be unique within a connection.
    
    HSQLDB-Specific Information:
    Including 2.0, HSQLDB does not support named cursors; calls to this method are ignored.
    
    Specified by:
    
    setCursorName in interface java.sql.Statement
    
    Parameters:
    
    name - the new cursor name, which must be unique within a connection
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed Statement
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - getResultSet
```
public java.sql.ResultSet getResultSet()
                                throws java.sql.SQLException
```
    Retrieves the current result as a ResultSet object. This method should be called only once per result.
    
    HSQLDB-Specific Information:
    Without an interceding call to executeXXX, each invocation of this method will produce a new, initialized ResultSet instance referring to the current result, if any.
    
    Specified by:
    
    getResultSet in interface java.sql.Statement
    
    Returns:
    
    the current result as a ResultSet object or null if the result is an update count or there are no more results
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed Statement
    
    See Also:
    
    execute()
  - getUpdateCount
```
public int getUpdateCount()
                   throws java.sql.SQLException
```
    Retrieves the current result as an update count; if the result is a ResultSet object or there are no more results, -1 is returned. This method should be called only once per result.
    
    Specified by:
    
    getUpdateCount in interface java.sql.Statement
    
    Returns:
    
    the current result as an update count; -1 if the current result is a ResultSet object or there are no more results

```
public boolean getMoreResults()
                       throws java.sql.SQLException
```
    Moves to this Statement object's next result, returns true if it is a ResultSet object, and implicitly closes any current ResultSet object(s) obtained with the method getResultSet.
    There are no more results when the following is true:
    // stmt is a Statement object ((stmt.getMoreResults() == false) && (stmt.getUpdateCount() == -1))
    Specified by:
    
    getMoreResults in interface java.sql.Statement
    
    Returns:
    
    true if the next result is a ResultSet object; false if it is an update count or there are no more results

  - setFetchDirection
```
public void setFetchDirection(int direction)
                       throws java.sql.SQLException
```
    Gives the driver a hint as to the direction in which rows will be processed in ResultSet objects created using this Statement object. The default value is ResultSet.FETCH_FORWARD.
    Note that this method sets the default fetch direction for result sets generated by this Statement object. Each result set has its own methods for getting and setting its own fetch direction.
    
    HSQLDB-Specific Information:
    Up to 1.8.0.x, HSQLDB supports only FETCH_FORWARD; Setting any other value would throw an SQLException stating that the operation is not supported.
    Starting with 2.0, HSQLDB accepts any valid value.
    
    Specified by:
    
    setFetchDirection in interface java.sql.Statement
    
    Parameters:
    
    direction - the initial direction for processing rows
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs, this method is called on a closed Statement or the given direction is not one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or ResultSet.FETCH_UNKNOWN

                      throws java.sql.SQLException
```
    Retrieves the direction for fetching rows from database tables that is the default for result sets generated from this Statement object. If this Statement object has not set a fetch direction by calling the method setFetchDirection, the return value is implementation-specific.
    
    HSQLDB-Specific Information:
    Up to 1.8.0.x, HSQLDB always returned FETCH_FORWARD. Starting with 2.0, HSQLDB returns FETCH_FORWARD by default, or whatever value has been explicitly assigned by invoking setFetchDirection. .
    
    Specified by:

```
public void setFetchSize(int rows)
                  throws java.sql.SQLException
```
    Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for ResultSet objects generated by this Statement. If the value specified is zero, then the hint is ignored. The default value is zero.
    
    HSQLDB-Specific Information:
    HSQLDB uses the specified value as a hint, but may process more or fewer rows than specified.
    
    Specified by:
    
    setFetchSize in interface java.sql.Statement
    
    Parameters:
    
    rows - the number of rows to fetch

public int getFetchSize()
                 throws java.sql.SQLException
```
    Retrieves the number of result set rows that is the default fetch size for ResultSet objects generated from this Statement object. If this Statement object has not set a fetch size by calling the method setFetchSize, the return value is implementation-specific.
    HSQLDB-Specific Information
    HSQLDB returns 0 by default, or the fetch size specified by setFetchSize
    
    Specified by:
    
    getFetchSize in interface java.sql.Statement

                 throws java.sql.SQLException
```
    Requests that a Statement be pooled or not pooled. The value specified is a hint to the statement pool implementation indicating whether the application wants the statement to be pooled. It is up to the statement pool manager as to whether the hint is used.
    The poolable value of a statement is applicable to both internal statement caches implemented by the driver and external statement caches implemented by application servers and other applications.
    By default, a Statement is not poolable when created, and a PreparedStatement and CallableStatement are poolable when created.
    
    Specified by:
    
    setPoolable in interface java.sql.Statement
    
    Parameters:
    
    poolable - requests that the statement be pooled if true and that the statement not be pooled if false

  - unwrap
```
public <T> T unwrap(java.lang.Class<T> iface)
             throws java.sql.SQLException
```
    Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
    
    Specified by:
    
    unwrap in interface java.sql.Wrapper
    
    Parameters:
    
    iface - A Class defining an interface that the result must implement.
    
    Returns:
    
    an object that implements the interface. May be a proxy for the actual implementing object.
    
    Throws:
    
    java.sql.SQLException - If no object found that implements the interface
    
    Since:

  - isWrapperFor
```
public boolean isWrapperFor(java.lang.Class<?> iface)
                     throws java.sql.SQLException
```
    Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.
    
    Specified by:
    
    isWrapperFor in interface java.sql.Wrapper
    
    Parameters:
    
    iface - a Class defining an interface.
    
    Returns:
    
    true if this implements the interface or directly or indirectly wraps an object that does.
    
    Throws:
    
    java.sql.SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

```
    Retrieves the current result as an update count; if the result is a ResultSet object or there are no more results, -1 is returned. This method should be called only once per result.
    This method should be used when the returned row count may exceed Integer.MAX_VALUE.
    The public implementation will throw UnsupportedOperationException
    
    Specified by:
    
    getLargeUpdateCount in interface java.sql.Statement
    
    Returns:
    
    the current result as an update count; -1 if the current result is a ResultSet object or there are no more results

                     throws java.sql.SQLException
```
    Sets the limit for the maximum number of rows that any ResultSet object generated by this Statement object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped.
    This method should be used when the row limit may exceed Integer.MAX_VALUE.
    The default implementation will throw UnsupportedOperationException
    
    Specified by:
    
    setLargeMaxRows in interface java.sql.Statement
    
    Parameters:
    
    max - the new max rows limit; zero means there is no limit
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs, this method is called on a closed Statement or the condition max >= 0 is not satisfied

```
    Retrieves the maximum number of rows that a ResultSet object produced by this Statement object can contain. If this limit is exceeded, the excess rows are silently dropped.
    This method should be used when the returned row limit may exceed Integer.MAX_VALUE.
    The default implementation will return 0
    
    Specified by:
    
    getLargeMaxRows in interface java.sql.Statement
    
    Returns:
    
    the current maximum number of rows for a ResultSet object produced by this Statement object; zero means there is no limit

  - executeLargeBatch
```
public long[] executeLargeBatch()
                         throws java.sql.SQLException
```
    Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The long elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeLargeBatch may be one of the following:
    
    A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
    A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown
    If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getLargeUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
    A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails
    
    This method should be used when the returned row count may exceed Integer.MAX_VALUE.
    The default implementation will throw UnsupportedOperationException
    Specified by:
    
    executeLargeBatch in interface java.sql.Statement
    
    Returns:
    
    an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs, this method is called on a closed Statement or the driver does not support batch statements. Throws BatchUpdateException (a subclass of SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.
    
    java.sql.SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement

```
public void setObject(int parameterIndex,
                      java.lang.Object x,
                      java.sql.SQLType targetSqlType,
                      int scaleOrLength)
               throws java.sql.SQLException
```
    Sets the value of the designated parameter with the given object. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.
    The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.
    Note that this method may be used to pass database-specific abstract data types.
    The default implementation will throw SQLFeatureNotSupportedException
    
    Specified by:
    
    setObject in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the object containing the input parameter value
    
    targetSqlType - the SQL type to be sent to the database. The scale argument may further qualify this type.
    
    scaleOrLength - for java.sql.JDBCType.DECIMAL or java.sql.JDBCType.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support the specified targetSqlType

               throws java.sql.SQLException
```
    Sets the value of the designated parameter with the given object. This method is similar to setObject(int parameterIndex, Object x, SQLType targetSqlType, int scaleOrLength), except that it assumes a scale of zero.
    The default implementation will throw SQLFeatureNotSupportedException
    
    Specified by:
    
    setObject in interface java.sql.PreparedStatement
    
    Parameters:
    
    parameterIndex - the first parameter is 1, the second is 2, ...
    
    x - the object containing the input parameter value
    
    targetSqlType - the SQL type to be sent to the database
    
    Throws:
    
    java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement

  - executeLargeUpdate
```
public long executeLargeUpdate()
                        throws java.sql.SQLException
```
    Executes the SQL statement in this PreparedStatement object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.
    This method should be used when the returned row count may exceed Integer.MAX_VALUE.
    The default implementation will throw UnsupportedOperationException
    
    Specified by:
    
    executeLargeUpdate in interface java.sql.PreparedStatement
    
    Returns:
    
    either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement returns a ResultSet object
    
    java.sql.SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement

    Specifies that this Statement will be closed when all its dependent result sets are closed. If execution of the Statement does not produce any result sets, this method has no effect.
    Note: Multiple calls to closeOnCompletion do not toggle the effect on this Statement. However, a call to closeOnCompletion does effect both the subsequent execution of statements, and statements that currently have open, dependent, result sets.
    
    Throws:
    
    java.sql.SQLException - if this method is called on a closed Statement

    Returns:
    
    true if the Statement will be closed when all of its dependent result sets are closed; false otherwise
    
    Throws:
