public class JDBCResultSet
extends java.lang.Object
implements java.sql.ResultSet
```
A table of data representing a database result set, which is usually generated by executing a statement that queries the database.
A ResultSet object maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The next method moves the cursor to the next row, and because it returns false when there are no more rows in the ResultSet object, it can be used in a while loop to iterate through the result set.
A default ResultSet object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce ResultSet objects that are scrollable and/or updatable. The following code fragment, in which con is a valid Connection object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See ResultSet fields for other options.
```
       Statement stmt = con.createStatement(
                                      ResultSet.TYPE_SCROLL_INSENSITIVE,
                                      ResultSet.CONCUR_UPDATABLE);
       ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
       // rs will be scrollable, will not show changes made by others,
       // and will be updatable

 
```
The ResultSet interface provides getter methods (getBoolean, getLong, and so on) for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.
For the getter methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the getter method and returns a suitable Java value. The JDBC specification has a table showing the allowable mappings from SQL types to Java types that can be used by the ResultSet getter methods.
Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQL AS clause.
A set of updater methods were added to this interface in the JDBC 2.0 API (Java 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.
The updater methods may be used in two ways:
1. to update a column value in the current row. In a scrollable ResultSet object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates the NAME column in the fifth row of the ResultSet object rs and then uses the method updateRow to update the data source table from which rs was derived.
```
       rs.absolute(5); // moves the cursor to the fifth row of rs
       rs.updateString("NAME", "AINSWORTH"); // updates the
          // NAME column of row 5 to be AINSWORTH
       rs.updateRow(); // updates the row in the data source

 
```
2. to insert column values into the insert row. An updatable ResultSet object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it into rs and into the data source table using the method insertRow.
```
       rs.moveToInsertRow(); // moves cursor to the insert row
       rs.updateString(1, "AINSWORTH"); // updates the
          // first column of the insert row to be AINSWORTH
       rs.updateInt(2,35); // updates the second column to be 35
       rs.updateBoolean(3, true); // updates the third column to true
       rs.insertRow();
       rs.moveToCurrentRow();

 
```
A ResultSet object is automatically closed when the Statement object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.
The number, types and properties of a ResultSet object's columns are provided by the ResultSetMetaData object returned by the ResultSet.getMetaData method.
HSQLDB-Specific Information:
A ResultSet object generated by HSQLDB is by default of ResultSet.TYPE_FORWARD_ONLY (as is standard JDBC behavior) and does not allow the use of absolute and relative positioning methods. If a statement is created with:
```
 Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
 
```
then the ResultSet objects it produces support using all of the absolute and relative positioning methods of JDBC2 to set the position of the current row, for example:
```
 rs.absolute(5);
 String fifthRowValue = rs.getString(1);
 rs.relative(4);
 String ninthRowValue = rs.getString(1);
 
```
A non-updatable HSQLDB ResultSet object stays open if it is not explicitly closed, even after its connection is closed. A connection opened with the property setting close_result=true closes any remaining open results when the connection is closed.
From HSQLDB 2.0, there is full support for updatable result sets. Supported methods include all updateXXX methods for the supported types, as well as the insertRow(), updateRow(), deleteRow(), moveToInsertRow() methods.
The Statement must be created with ResultSet.CONCUR_UPDATABLE instead of CONCUR_READ_ONLY.
Updatability of a result set follows the SQL standards. Some or all columns of an updatable result set can be updated. The current row in such result sets can be deleted using the deleteRow() method. Some updatable result set can also be inserted into and support moveToInsertRow().
A result set is updatable if the SELECT statement is updatable. This includes SELECT from TABLE and updatable VIEW objects. An updatable SELECT statement has a single underlying table or view. HSQLDB supports both scrollable and forward-only result sets for updatability.
```
 -- In the SELECT below, columns A and B are updatable, any row can be
 -- deleted, but it is not insertable-into as column C is not directly from
 -- the table.
 SELECT A, B, A + B AS C FROM T WHERE ...

 -- The SELECT below can be insertable-into so long as other columns of the
 -- table that do not appear in the SELECT list have a default value.
 SELECT A, B FROM T WHERE ...
 
```
From version 2.7.4, support for updatable result sets is extended to make updates and deletes visible. This feature is useful with scrollable result sets. After calling updateRow, the rowUpdated method now returns true on an updated row. After calling deleteRow, the rowDeleted method now returns true on a deleted row. Calling a getXXX method returns the updated values for updated rows and null for deleted rows. (fredt@users)

- Method Detail
  - next
```
public boolean next()
             throws java.sql.SQLException
```
    Moves the cursor forward one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.
    When a call to the next method returns false, the cursor is positioned after the last row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown. If the result set type is TYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will return false or throw an SQLException on a subsequent call to next.
    If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.
    
    Specified by:
    
    next in interface java.sql.ResultSet
    
    Returns:
    
    true if the new current row is valid; false if there are no more rows
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed result set
  - close
```
public void close()
           throws java.sql.SQLException
```
    Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.
    The closing of a ResultSet object does not close the Blob, Clob or NClob objects created by the ResultSet. Blob, Clob or NClob objects remain valid for at least the duration of the transaction in which they are created, unless their free method is invoked.
    When a ResultSet is closed, any ResultSetMetaData instances that were created by calling the getMetaData method remain accessible.
    Note: A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.
    Calling the method close on a ResultSet object that is already closed is a no-op.
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Specified by:
    
    close in interface java.sql.ResultSet

public boolean wasNull()
                throws java.sql.SQLException
```
    Reports whether the last column read had a value of SQL NULL. Note that you must first call one of the getter methods on a column to try to read its value and then call the method wasNull to see if the value read was SQL NULL.
    
    Specified by:
    
    wasNull in interface java.sql.ResultSet
    
    Returns:
    
    true if the last column value read was SQL NULL and false otherwise

```
    Retrieves the value of the designated column in the current row of this ResultSet object as a java.sql.Timestamp object in the Java programming language.
    
    HSQLDB-Specific Information:
    The JDBC specification for this method is vague. HSQLDB interprets the specification as follows:
    
    If the SQL type of the column is WITH TIME ZONE, then the UTC value of the returned java.sql.Timestamp object is the UTC of the SQL value without modification.
    
    If the SQL type of the column is WITHOUT TIME ZONE, then the UTC value of the returned java.sql.Timestamp will represent the correct timestamp for the time zone (including daylight saving time) of the SQL session.
    Specified by:
    
    getTimestamp in interface java.sql.ResultSet
    
    Parameters:
    
    columnIndex - the first column is 1, the second is 2, ...
    
    Returns:
    
    the column value; if the value is SQL NULL, the value returned is null
    
    Throws:
    
    java.sql.SQLException - if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set
  - getAsciiStream
```
public java.io.InputStream getAsciiStream(int columnIndex)
                                   throws java.sql.SQLException
```
    Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.
    Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called whether there is data available or not.
    
    HSQLDB-Specific Information:
    The limitation noted above does not apply to HSQLDB.
    When the column is of type CHAR and its variations, it requires no conversion since it is represented internally already as a Java String object. When the column is not of type CHAR and its variations, the returned stream is based on a conversion to the Java String representation of the value. In either case, the obtained stream is always equivalent to a stream of the low order bytes from the value's String representation.
    HSQLDB SQL CHAR and its variations are all Unicode strings internally, so the recommended alternatives to this method are getString, getUnicodeStream (deprecated) and new to 1.7.0: getCharacterStream (now preferred over the deprecated getUnicodeStream alternative).
    
    Specified by:
    
    getAsciiStream in interface java.sql.ResultSet
    
    Parameters:
    
    columnIndex - the first column is 1, the second is 2, ...
    
    Returns:

```
    Deprecated.
    use getCharacterStream in place of getUnicodeStream
    
    Retrieves the value of the designated column in the current row of this ResultSet object as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHARvalues. The JDBC driver will do any necessary conversion from the database format into Unicode.
    Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.
    
    HSQLDB-Specific Information:
    The limitation noted above does not apply to HSQLDB.
    When the column is of type CHAR and its variations, it requires no conversion since it is represented internally already as Java Strings. When the column is not of type CHAR and its variations, the returned stream is based on a conversion to the Java String representation of the value. In either case, the obtained stream is always equivalent to a stream of bytes from the value's String representation, with high-byte first.
    
    Specified by:
    
    getUnicodeStream in interface java.sql.ResultSet
    
    Parameters:
    
    columnIndex - the first column is 1, the second is 2, ...

    HSQLDB-Specific Information:
    The JDBC specification for this method is vague. HSQLDB interprets the specification as follows:
    
    If the SQL type of the column is WITH TIME ZONE, then the UTC value of the returned java.sql.Timestamp object is the UTC of the SQL value without modification.
    
    If the SQL type of the column is WITHOUT TIME ZONE, then the UTC value of the returned java.sql.Timestamp will represent the correct timestamp for the time zone (including daylight saving time) of the SQL session.
    Specified by:
    
    getTimestamp in interface java.sql.ResultSet
    
    Parameters:
    
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column

                                   throws java.sql.SQLException
```
    Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.
    Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.
    
    Specified by:
    
    getAsciiStream in interface java.sql.ResultSet
    
    Parameters:

    Deprecated.
    use getCharacterStream instead
    
    Retrieves the value of the designated column in the current row of this ResultSet object as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC technology-enabled driver will do any necessary conversion from the database format into Unicode.
    Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

```
    Retrieves the value of the designated column in the current row of this ResultSet object as a stream of uninterpreted bytes. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARBINARY values.
    Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.
    
    Specified by:
    
    getBinaryStream in interface java.sql.ResultSet
    
    Parameters:
    
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    
    Returns:
    
    a Java input stream that delivers the database column value as a stream of uninterpreted bytes; if the value is SQL NULL, the result is null

  - getWarnings
```
public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
```
    Retrieves the first warning reported by calls on this ResultSet object. Subsequent warnings on this ResultSet object will be chained to the SQLWarning object that this method returns.
    The warning chain is automatically cleared each time a new row is read. This method may not be called on a ResultSet object that has been closed; doing so will cause an SQLException to be thrown.
    Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by Statement methods (such as reading OUT parameters) will be chained on the Statement object.
    
    HSQLDB-Specific Information:
    HSQLDB does not produce SQLWarning objects on any ResultSet object warning chain; this method always returns null.
    
    Specified by:
    
    getWarnings in interface java.sql.ResultSet
    
    Returns:
    
    the first SQLWarning object reported or null if there are none
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed result set
  - clearWarnings
```
public void clearWarnings()
                   throws java.sql.SQLException
```
    Clears all warnings reported on this ResultSet object. After this method is called, the method getWarnings returns null until a new warning is reported for this ResultSet object.
    
    HSQLDB-Specific Information:
    HSQLDB does not produce SQLWarning objects on any ResultSet object warning chain; calls to this method are ignored.
    
    Specified by:
    
    clearWarnings in interface java.sql.ResultSet
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed result set
  - getCursorName
```
public java.lang.String getCursorName()
                               throws java.sql.SQLException
```
    Retrieves the name of the SQL cursor used by this ResultSet object.
    In SQL, a result table is retrieved through a cursor that is named. The current row of a result set can be updated or deleted using a positioned update/delete statement that references the cursor name. To ensure that the cursor has the proper isolation level to support update, the cursor's SELECT statement should be of the form SELECT FOR UPDATE. If FOR UPDATE is omitted, the positioned updates may fail.
    The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a ResultSet object is also the current row of this SQL cursor.
    
    HSQLDB-Specific Information:
    HSQLDB supports this feature when the cursor has a name.
    
    Specified by:
    
    getCursorName in interface java.sql.ResultSet
    
    Returns:
    
    the SQL name for this ResultSet object's cursor
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed result set
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - getMetaData
```
public java.sql.ResultSetMetaData getMetaData()
                                       throws java.sql.SQLException
```
    Retrieves the number, types and properties of this ResultSet object's columns.
    
    HSQLDB-Specific Information:
    Example:
    The following code fragment creates a ResultSet object rs, creates a ResultSetMetaData object rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in a WHERE clause.
    ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2"); ResultSetMetaData rsmd = rs.getMetaData();
    int numberOfColumns = rsmd.getColumnCount();
    boolean b = rsmd.isSearchable(1);
    
    Changes:
    With version 2.0, the engine's SQL implementation has been completely rewritten. Changes to this class and the implementation of ResultSetMetaData reflect the engine's new capabilities and provide more accurate information.
    changes to consider:
    
    isAutoIncrement(int) always returned false
    
    isNullable(int) returns the nullability of a real table or view column in the ResultSet and returns columnNoNulls for non-base-column ResultSet columns (columns of the ResultSet that are based on expressions or aggregates).
    
    getColumnDisplaySize(int) returns correct results even for expression columns.
    
    getPrecision(int) returns the correct precision even for expression columns.
    
    getScale(int) returns the correct precision even for expression columns.
    
    getCatalogName(int) returns the catalog name of the database.
    Specified by:
    
    getMetaData in interface java.sql.ResultSet
    
    Returns:
    
    the description of this ResultSet object's columns
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed result set
  - getObject
```
public java.lang.Object getObject(int columnIndex)
                           throws java.sql.SQLException
```
    Gets the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language.
    This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL, the driver returns a Java null.
    This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types.
    If Connection.getTypeMap does not throw a SQLFeatureNotSupportedException, then when a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()). If Connection.getTypeMap does throw a SQLFeatureNotSupportedException, then structured values are not supported, and distinct values are mapped to the default Java class as determined by the underlying SQL type of the DISTINCT type.
    
    Specified by:
    
    getObject in interface java.sql.ResultSet
    
    Parameters:

                           throws java.sql.SQLException
```
    Gets the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language.
    This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL, the driver returns a Java null.
    This method may also be used to read database-specific abstract data types.
    In the JDBC 2.0 API, the behavior of the method getObject is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).
    
    Specified by:
    
    getObject in interface java.sql.ResultSet
    
    Parameters:
    
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    
    Returns:
    
    a java.lang.Object holding the column value
    
    Throws:
    
    java.sql.SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set
  - findColumn
```
public int findColumn(java.lang.String columnLabel)
               throws java.sql.SQLException
```
    Maps the given ResultSet column label to its ResultSet column index.
    
    HSQLDB-Specific Information:
    Starting with 1.9.x, HSQLDB does an exhaustive search, backed by a cache lookup (to improve performance for subsequent invocations with a given input).
    Upon careful investigation of the JDBC specification and the behaviour of existing JDBC drivers, there is actually nothing preventing the findColumn method from doing an exhaustive search, as long as it conforms to the following rules (which describe the new implementation):
    
    the entire search is case insensitive
    each search iteration occurs from leftmost to rightmost column, returning the first match encountered
    the first pass matches only bare column labels
    the second pass matches only simple column names
    further passes conform to the identifier qualification and identifier quoting rules of the engine
    In this implementation, the SQL tokenizer is not employed, both because it does not yet correctly handle greater than two part qualification and also because is is not immediately considered important to do a truly exhaustive search, handling the full range of possibly mixed quoted and unquoted identifier components.
    Instead:
    
    a third pass matches simple table-dot-column qualified names
    a fourth pass matches simple schema-dot-table-dot-column qualified column names
    Specified by:
    
    findColumn in interface java.sql.ResultSet
    
    Parameters:
    
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    
    Returns:
    
    the column index of the given column name
    
    Throws:
    
    java.sql.SQLException - if the ResultSet object does not contain a column labeled columnLabel, a database access error occurs or this method is called on a closed result set

  - absolute
```
public boolean absolute(int row)
                 throws java.sql.SQLException
```
    Moves the cursor to the given row number in this ResultSet object.
    If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.
    If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method absolute(-1) positions the cursor on the last row; calling the method absolute(-2) moves the cursor to the next-to-last row, and so on.
    If the row number specified is zero, the cursor is moved to before the first row.
    An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.
    Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().
    
    Specified by:
    
    absolute in interface java.sql.ResultSet
    
    Parameters:
    
    row - the number of the row to which the cursor should move. A value of zero indicates that the cursor will be positioned before the first row; a positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
    
    Returns:
    
    true if the cursor is moved to a position in this ResultSet object; false if the cursor is before the first row or after the last row
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY

    JDK 1.2
  - relative
```
public boolean relative(int rows)
                 throws java.sql.SQLException
```
    Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the first/last row. Calling relative(0) is valid, but does not change the cursor position.
    Note: Calling the method relative(1) is identical to calling the method next() and calling the method relative(-1) is identical to calling the method previous().
    
    Specified by:
    
    relative in interface java.sql.ResultSet
    
    Parameters:
    
    rows - an int specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward
    
    Returns:
    
    true if the cursor is on a row; false otherwise
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    
    Since:
    
    JDK 1.2
  - previous
```
public boolean previous()
                 throws java.sql.SQLException
```
    Moves the cursor to the previous row in this ResultSet object.
    When a call to the previous method returns false, the cursor is positioned before the first row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown.
    If an input stream is open for the current row, a call to the method previous will implicitly close it. A ResultSet object's warning change is cleared when a new row is read.
    
    Specified by:
    
    previous in interface java.sql.ResultSet
    
    Returns:
    
    true if the cursor is now positioned on a valid row; false if the cursor is positioned before the first row
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY
    
    java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method

  - setFetchDirection
```
public void setFetchDirection(int direction)
                       throws java.sql.SQLException
```
    Gives a hint as to the direction in which the rows in this ResultSet object will be processed. The initial value is determined by the Statement object that produced this ResultSet object. The fetch direction may be changed at any time.
    
    HSQLDB-Specific Information:
    HSQLDB does not need this hint. However, as mandated by the JDBC standard, an SQLException is thrown if the result set type is TYPE_FORWARD_ONLY and a fetch direction other than FETCH_FORWARD is requested.
    
    Specified by:
    
    setFetchDirection in interface java.sql.ResultSet
    
    Parameters:
    
    direction - an int specifying the suggested fetch direction; one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or ResultSet.FETCH_UNKNOWN
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY and the fetch direction is not FETCH_FORWARD
    
    Since:

public int getFetchDirection()
                      throws java.sql.SQLException
```
    Retrieves the fetch direction for this ResultSet object.
    
    HSQLDB-Specific Information:
    HSQLDB does not depend on fetch direction and always returns FETCH_FORWARD, but the value has no real meaning.
    
    Specified by:
    
    getFetchDirection in interface java.sql.ResultSet
    
    Returns:
    
    the current fetch direction for this ResultSet object

    setFetchDirection(int)
  - setFetchSize
```
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 this ResultSet object. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. The default value is set by the Statement object that created the result set. The fetch size may be changed at any time.
    
    HSQLDB-Specific Information:
    HSQLDB may not build and return a result set as a whole. Therefore the supplied, non-zero, fetch size value is used for some ResultSet objects.
    
    Specified by:
    
    setFetchSize in interface java.sql.ResultSet
    
    Parameters:
    
    rows - the number of rows to fetch
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; this method is called on a closed result set or the condition rows >= 0 is not satisfied

```
public int getConcurrency()
                   throws java.sql.SQLException
```
    Retrieves the concurrency mode of this ResultSet object. The concurrency used is determined by the Statement object that created the result set.
    
    HSQLDB-Specific Information:
    HSQLDB supports updatable result sets and accurately reports the actual runtime concurrency of this result set instance.
    
    Specified by:
    
    getConcurrency in interface java.sql.ResultSet
    
    Returns:
    
    the concurrency type, either ResultSet.CONCUR_READ_ONLY or ResultSet.CONCUR_UPDATABLE
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs or this method is called on a closed result set

  - rowUpdated
```
public boolean rowUpdated()
                   throws java.sql.SQLException
```
    Retrieves whether the current row has been updated. The value returned depends on whether or not the result set can detect updates.
    Note: Support for the rowUpdated method is optional with a result set concurrency of CONCUR_READ_ONLY

    Updates the underlying database with the new contents of the current row of this ResultSet object. This method cannot be called when the cursor is on the insert row.
    
    HSQLDB-Specific Information:
    HSQLDB supports this feature.
    After updating any values in the current row, it is not possible to move the cursor position without calling this method, or alternatively calling cancelRowUpdates() to abandon the row update.
    After calling this method, the getXXX methods return the updated values for the updated row.

```
public void deleteRow()
               throws java.sql.SQLException
```
    Deletes the current row from this ResultSet object and from the underlying database. This method cannot be called when the cursor is on the insert row.
    
    HSQLDB-Specific Information:
    HSQLDB supports this feature.
    After a successful call to this method, the row is deleted. All column values returned by getXXX methods are null for a row that has been deleted.
    
    Specified by:
    
    deleteRow in interface java.sql.ResultSet
    
    Throws:
    
    java.sql.SQLException - if a database access error occurs; the result set concurrency is CONCUR_READ_ONLY; this method is called on a closed result set or if this method is called when the cursor is on the insert row

  - refreshRow
```
public void refreshRow()
                throws java.sql.SQLException
```
    Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.
    The refreshRow method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.
    All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow is called after calling an updater method, but before calling the method updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.
    
    HSQLDB-Specific Information:
    HSQLDB supports this feature.
    
    Specified by:
    
    refreshRow in interface java.sql.ResultSet
    
    Throws:

  - cancelRowUpdates
```
public void cancelRowUpdates()
                      throws java.sql.SQLException
```
    Cancels the updates made to the current row in this ResultSet object. This method may be called after calling an updater method(s) and before calling the method updateRow to roll back the updates made to a row. If no updates have been made or updateRow has already been called, this method has no effect.
    
    HSQLDB-Specific Information:

  - moveToInsertRow
```
public void moveToInsertRow()
                     throws java.sql.SQLException
```
    Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updater methods prior to inserting the row into the result set. Only the updater, getter, and insertRow methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow. An updater method must be called before a getter method can be called on a column value.
    
    HSQLDB-Specific Information:
    HSQLDB supports this feature.
    
    Specified by:
    
    moveToInsertRow in interface java.sql.ResultSet

    Retrieves the value of the designated column in the current row of this ResultSet object as a java.sql.Timestamp object in the Java programming language. This method uses the given calendar to construct an appropriate millisecond value for the timestamp if the underlying database does not store timezone information.
    
    HSQLDB-Specific Information:
    The JDBC specification for this method is vague. HSQLDB interprets the specification as follows:
    
    If the SQL type of the column is WITH TIME ZONE, then the UTC value of the returned java.sql.Timestamp object is the UTC of the SQL value without modification. In other words, the Calendar object is not used.
    
    If the SQL type of the column is WITHOUT TIME ZONE, then the UTC value of the returned java.sql.Timestamp will represent the correct timestamp for the time zone (including daylight saving time) of the given Calendar object.
    
    In this case, if the cal argument is null, then the default Calendar of the JVM is used, which results in the same Object as one returned by the getTimestamp() methods without the Calendar parameter.
    Specified by:
    
    getTimestamp in interface java.sql.ResultSet
    
    Parameters:
    
    columnIndex - the first column is 1, the second is 2, ...
    
    cal - the java.util.Calendar object to use in constructing the timestamp
    
    Returns:
    
    the column value as a java.sql.Timestamp object; if the value is SQL NULL, the value returned is null in the Java programming language
    
    Throws:
    
    java.sql.SQLException - if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set

    updateNClob in interface java.sql.ResultSet
    
    Parameters:
    
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    
    reader - An object that contains the data to set the parameter value to.
    
    Throws:
    
    java.sql.SQLException - if the columnLabel is not valid; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; this method is called on a closed result set; if a database access error occurs or the result set concurrency is CONCUR_READ_ONLY

  - 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 value of the designated column in the current row of this ResultSet object and will convert from the SQL type of the column to the requested Java data type, if the conversion is supported. If the conversion is not supported or null is specified for the type, a SQLException is thrown.
    At a minimum, an implementation must support the conversions defined in Appendix B, Table B-3 and conversion of appropriate user defined SQL types to a Java type which implements SQLData, or Struct. Additional conversions may be supported and are vendor defined.

    T - the type of the class modeled by this Class object
    
    Parameters:
    
    columnIndex - the first column is 1, the second is 2, ...
    
    type - Class representing the Java data type to convert the designated column to.
    
    Returns:
    
    an instance of type holding the column value
    
    Throws:
    
    java.sql.SQLException - if conversion is not supported, type is null or another error occurs. The getCause() method of the exception may provide a more detailed exception, for example, if a conversion error occurs
