All Implemented Interfaces:
  java.sql.ResultSet

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, there is no way for the programmer to guarantee that they actually refer to the intended columns.

A set of updater methods were added to this interface in the JDBC 2.0 API (JavaTM 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 row 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 `ResulSetMetaData` 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. However, since 1.7.0, 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);

Note: An HSQLDB `ResultSet` object persists, even after its connection is closed. This is regardless of the operational mode of the `Database` from which it came. That is, they persist whether originating from a `Server`, `WebServer` or in-process mode `Database.`

Including HSQLDB 1.7.2, there is no support for any of the methods introduced in JDBC 2 relating to updateable result sets. These methods include all updateXXX methods, as well as the `insertRow()`, `updateRow()`, `deleteRow()`, `moveToInsertRow()` (and so on) methods; invoking any such method throws an `SQLException` stating that the operation is not supported. JRE 1.1.x Notes:

In general, JDBC 2 support requires Java 1.2 and above, and JDBC 3 requires Java 1.4 and above. In HSQLDB, support for methods introduced in different versions of JDBC depends on the JDK version used for compiling and building HSQLDB.

Since 1.7.0, it is possible to build the product so that all JDBC 2 methods can be called while executing under the version 1.1.x Java Runtime EnvironmentTM. However, some of these method calls require `int` values that are defined only in the JDBC 2 or greater version of the `ResultSet` interface. For this reason, when the product is compiled under JDK 1.1.x, these values are defined here, in this class.

In a JRE 1.1.x environment, calling JDBC 2 methods that take or return the JDBC2-only `ResultSet` values can be achieved by referring to them in parameter specifications and return value comparisons, respectively, as follows:

     jdbcResultSet.FETCH_FORWARD
     jdbcResultSet.TYPE_FORWARD_ONLY
     jdbcResultSet.TYPE_SCROLL_INSENSITIVE
     jdbcResultSet.CONCUR_READ_ONLY
     // etc.

However, please note that code written in such a manner will not be compatible for use with other JDBC 2 drivers, since they expect and use `ResultSet`, rather than `jdbcResultSet`. Also note, this feature is offered solely as a convenience to developers who must work under JDK 1.1.x due to operating constraints, yet wish to use some of the more advanced features available under the JDBC 2 specification.

Method Detail

### next

    public boolean next()
                 throws java.sql.SQLException

  Moves the cursor down 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.

  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

### 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.

  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. A `ResultSet` object is also automatically closed when it is garbage collected.

  Specified by:
    `close` in interface `java.sql.ResultSet`
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### wasNull

    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
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### 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.

  In 1.6.1 and previous, getAsciiStream was identical to getUnicodeStream and both simply returned a byte stream constructed from the raw `getBytes` representation. Starting with 1.7.0, this has been updated to comply with the java.sql specification. 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 prefered 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:
    a Java input stream that delivers the database column value as a stream of one-byte ASCII characters; if the value is SQL `NULL`, the value returned is `null`
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### getUnicodeStream

    public java.io.InputStream getUnicodeStream(int columnIndex)
                                         throws java.sql.SQLException

  Deprecated. use `getCharacterStream` in place of `getUnicodeStream`

  Retrieves the value of the designated column in the current row of this `ResultSet` object as 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 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.

  Up to and including 1.6.1, getUnicodeStream (and getAsciiStream) both simply returned a byte stream constructed from the raw `getBytes` representation. Starting with 1.7.0, this has been corrected to comply with the java.sql specification. 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, ...
  Returns:
    a Java input stream that delivers the database column value as a stream of two-byte Unicode characters; if the value is SQL `NULL`, the value returned is `null`
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### getBinaryStream

    public java.io.InputStream getBinaryStream(int columnIndex)
                                        throws java.sql.SQLException

  Retrieves the value of the designated column in the current row of this `ResultSet` object as a binary 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 `InputStream.available` is called whether there is data available or not.

  Specified by:
    `getBinaryStream` in interface `java.sql.ResultSet`
  Parameters:
    `columnIndex` - the first column is 1, the second is 2, ...
  Returns:
    a Java input stream that delivers the database column value as a stream of uninterpreted bytes; if the value is SQL `NULL`, the value returned is `null`

  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:
    `columnName` - the SQL 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`
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### 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:

  Up to and including 1.7.1, HSQLDB does not produce `SQLWarning` objects. 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

    Up to and including 1.7.1, HSQLDB always returns null.

  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:

  Including 1.7.1, 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

### 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 insure 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.

  Note: If positioned update is not supported, a `SQLException` is thrown.

  ### HSQLDB-Specific Information:

  Including 1.7.2, HSQLDB does not support this feature.

  Calling this method always throws an `SQLException`, stating that the operation is not supported.

  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

### 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);

  Warning:

  Including 1.7.1, HSQLDB did not generate accurate `ResultSetMetaData`. Below were the the most important methods to consider:

  1. isAutoIncrement(int) always returned `false`
  2. isCurrency(int) always returned `false`
  3. isNullable(int) always returned `columnNullableUnknown`
  4. getColumnDisplaySize(int) returned zero for all valid column numbers
  5. getSchemaName(int) always returned ""
  6. getPrecision(int) always returned zero
  7. getScale(int) always returned zero
  8. getCatalogName(int) always returned ""

  Starting with 1.7.2, ResultSetMetaData has been split out into its own interface implemenation (jdbcResultSetMetaData), support has been improved considerably for a number of methods and behaviour has been altered slightly in many areas.

  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
  See Also:
    `jdbcResultSetMetaData`

### 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 datatabase-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. 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:
    `columnIndex` - the first column is 1, the second is 2, ...
  Returns:
    a `java.lang.Object` holding the column value
  Throws:
    `java.sql.SQLException` - if a database access error occurs

### getObject

    public java.lang.Object getObject(java.lang.String columnName)
                               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 datatabase-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:
    `columnName` - the SQL name of the column
  Returns:
    a `java.lang.Object` holding the column value

                   throws java.sql.SQLException

  Retrieves whether the cursor is on the last row of this `ResultSet` object. Note: Calling the method `isLast` may be expensive because the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.

  ### HSQLDB-Specific Information:

  Including 1.7.2, this method is not terribly expensive; the entire result is fetched internally before this object is returned to a caller.

  Specified by:
    `isLast` in interface `java.sql.ResultSet`
  Returns:
    `true` if the cursor is on the last row; `false` otherwise
  Throws:

  Moves the cursor to the first row in this `ResultSet` object.

  Specified by:
    `first` in interface `java.sql.ResultSet`
  Returns:
    `true` if the cursor is on a valid row; `false` if there are no rows in the result set
  Throws:
    `java.sql.SQLException` - if a database access error occurs or the result set type is `TYPE_FORWARD_ONLY`
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

### last

    public boolean last()
                 throws java.sql.SQLException

  Specified by:
    `getRow` in interface `java.sql.ResultSet`
  Returns:
    the current row number; `0` if there is no current row
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  Since:

### 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.

  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 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 on the result set; `false` otherwise
  Throws:
    `java.sql.SQLException` - if a database access error occurs, or the result set type is `TYPE_FORWARD_ONLY`
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

### 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 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, there is no current row, or the result set type is `TYPE_FORWARD_ONLY`
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

    public boolean previous()
                     throws java.sql.SQLException

  Moves the cursor to the previous row in this `ResultSet` object.

  Specified by:
    `previous` in interface `java.sql.ResultSet`
  Returns:
    `true` if the cursor is on a valid row; `false` if it is off the result set
  Throws:
    `java.sql.SQLException` - if a database access error occurs or the result set type is `TYPE_FORWARD_ONLY`
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

### 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:

  Including 1.7.2, HSQLDB builds and returns result sets as a whole; this method does nothing. 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 or the result set type is `TYPE_FORWARD_ONLY` and the fetch direction is not `FETCH_FORWARD`
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)
  See Also:
    `jdbcStatement.setFetchDirection(int)`, `getFetchDirection()`

### getFetchDirection

    public int getFetchDirection()
                          throws java.sql.SQLException

  Retrieves the fetch direction for this `ResultSet` object.

  ### HSQLDB-Specific Information:

  Including 1.7.2, HSQLDB builds and returns result sets as a whole; this method 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
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)
  See Also:
    `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:

  Including 1.7.2, HSQLDB builds and returns result sets as a whole; this method does nothing.

  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 or the condition `0 <= rows <= this.getMaxRows()` is not satisfied
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

                     throws java.sql.SQLException

  Retrieves the fetch size for this `ResultSet` object.

  ### HSQLDB-Specific Information:

  Including 1.7.2, HSQLDB builds and returns result sets as a whole; the value returned (always 1) has no significance.

  Specified by:
    `getFetchSize` in interface `java.sql.ResultSet`
  Returns:
    the current fetch size for this `ResultSet` object
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)
  See Also:
    `setFetchSize(int)`, `jdbcStatement.getFetchSize()`, `jdbcStatement.setFetchSize(int)`

### getType

    public int getType()
                throws java.sql.SQLException

  Retrieves the type of this `ResultSet` object. The type is determined by the `Statement` object that created the result set.

  ### HSQLDB-Specific Information:

  Including 1.7.2, HSQLDB does not support and thus never returns `ResultSet.TYPE_SCROLL_SENSITIVE`.

  Specified by:
    `getType` in interface `java.sql.ResultSet`
  Returns:
    `ResultSet.TYPE_FORWARD_ONLY`, `ResultSet.TYPE_SCROLL_INSENSITIVE`, or `ResultSet.TYPE_SCROLL_SENSITIVE` (not supported)

### getConcurrency

    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:

  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
  Since:
    JDK 1.2 (JDK 1.1.x developers: read the new overview for jdbcResultSet)

### 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.

  ### HSQLDB-Specific Information:

  Including 1.7.2, HSQLDB does not support updateable results.

  This method always returns false.

  Specified by:
    `rowUpdated` in interface `java.sql.ResultSet`
  Returns:
    `true` if both (1) the row has been visibly updated by the owner or another and (2) updates are detected
  Throws:

### 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:

  Including 1.7.2, HSQLDB does not support updateable result sets.

  This method always throws an SQLException stating that the operation is not supported.

  Specified by:
    `refreshRow` in interface `java.sql.ResultSet`

    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:
