Throws:

SQLException

Method Details

absolute

public boolean absolute(int row)
                 throws SQLException

JDBC 2.0

Move to an absolute row number in the result set.

If row is positive, moves to an absolute row with respect to the beginning of the result set. The first row is row 1, the second is row 2, etc.

If row is negative, moves to an absolute row position with respect to the end of result set. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) indicates the next-to-last row, etc.

An attempt to position the cursor beyond the first/last row in the result set, leaves the cursor before/after the first/last row, respectively.

Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().

Specified by:

absolute in interface ResultSet

Overrides:

absolute in class ResultSetImpl

Parameters:

row -

Returns:

true if on the result set, false if off.

isAfterLast

public boolean isAfterLast()
                    throws SQLException

JDBC 2.0

Determine if the cursor is after the last row in the result set.

Specified by:

true if after the last row, false otherwise. Returns false when the result set contains no rows.

Throws:

SQLException - if a database-access error occurs.

isBeforeFirst

public boolean isBeforeFirst()
                      throws SQLException

JDBC 2.0

Determine if the cursor is before the first row in the result set.

Specified by:

isLast in interface ResultSet

Overrides:

isLast in class ResultSetImpl

Returns:

true if on the last row, false otherwise.

Throws:

SQLException - if a database-access error occurs.

isUpdatable

boolean isUpdatable()

last

public boolean last()
             throws SQLException

JDBC 2.0

Moves to the last row in the result set.

Specified by:

last in interface ResultSet

Overrides:

last in class ResultSetImpl

moveToCurrentRow

public void moveToCurrentRow()
                      throws SQLException

JDBC 2.0 Move the cursor to the remembered cursor position, usually the current row. Has no effect unless the cursor is on the insert row.

Specified by:

moveToCurrentRow in interface ResultSet

Overrides:

moveToCurrentRow in class ResultSetImpl

Throws:

SQLException - if a database-access error occurs, or the result set is not updatable

SQLException - if the ResultSet is not updatable or some other error occurs

moveToInsertRow

public void moveToInsertRow()
                     throws SQLException

JDBC 2.0 Move 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 updateXXX() methods prior to inserting the row into the result set. Only the updateXXX(), getXXX(), 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(). UpdateXXX()must be called before getXXX() on a column.

Specified by:

moveToInsertRow in interface ResultSet

Overrides:

moveToInsertRow in class ResultSetImpl

Throws:

SQLException - if a database-access error occurs, or the result set is not updatable

NotUpdatable

next

public boolean next()
             throws SQLException

A ResultSet is initially positioned before its first row, the first call to next makes the first row the current row; the second call makes the second row the current row, etc.

If an input stream from the previous row is open, it is implicitly closed. The ResultSet's warning chain is cleared when a new row is read

Specified by:

next in interface ResultSet

Overrides:

next in class ResultSetImpl

Returns:

true if the new current is valid; false if there are no more rows

Throws:

SQLException - if a database access error occurs

prev

public boolean prev()
             throws SQLException

The prev method is not part of JDBC, but because of the architecture of this driver it is possible to move both forward and backward within the result set.

If an input stream from the previous row is open, it is implicitly closed. The ResultSet's warning chain is cleared when a new row is read

Overrides:

prev in class ResultSetImpl

Returns:

true if the new current is valid; false if there are no more rows

Throws:

SQLException - if a database access error occurs

previous

public boolean previous()
                 throws SQLException

JDBC 2.0

Moves to the previous row in the result set.

Note: previous() is not the same as relative(-1) since it makes sense to call previous() when there is no current row.

Specified by:

previous in interface ResultSet

Overrides:

previous in class ResultSetImpl

Returns:

true if on a valid row, false if off the result set.

Throws:

SQLException - if a database-access error occurs, or result set type is TYPE_FORWAR_DONLY.

realClose

public void realClose(boolean calledExplicitly)
               throws SQLException

Closes this ResultSet and releases resources.

Specified by:

realClose in interface ResultSetInternalMethods

Overrides:

realClose in class ResultSetImpl

Parameters:

calledExplicitly - was realClose called by the standard ResultSet.close() method, or was it closed internally by the driver?

Throws:

SQLException - if an error occurs.

refreshRow

public void refreshRow()
                throws SQLException

JDBC 2.0 Refresh the value of the current row with its current value in the database. Cannot be called when 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 updateXXX(), but before calling updateRow() then the updates made to the row are lost. Calling refreshRow() frequently will likely slow performance.

Specified by:

refreshRow in interface ResultSet

Overrides:

refreshRow in class ResultSetImpl

Throws:

SQLException - if a database-access error occurs, or if called when on the insert row.

NotUpdatable

relative

public boolean relative(int rows)
                 throws SQLException

JDBC 2.0

Moves 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 relative(1) is different than calling next() since is makes sense to call next() when there is no current row, for example, when the cursor is positioned before the first row or after the last row of the result set.

Specified by:

relative in interface ResultSet

Overrides:

relative in class ResultSetImpl

Parameters:

rows -

Returns:

true if on a row, false otherwise.

Throws:

SQLException - if a database-access error occurs, or there is no current row, or result set type is TYPE_FORWARD_ONLY.

rowDeleted

public boolean rowDeleted()
                   throws SQLException

JDBC 2.0 Determine if this row has been deleted. A deleted row may leave a visible "hole" in a result set. This method can be used to detect holes in a result set. The value returned depends on whether or not the result set can detect deletions.

Specified by:

rowDeleted in interface ResultSet

Overrides:

rowDeleted in class ResultSetImpl

Returns:

true if deleted and deletes are detected

Throws:

SQLException - if a database-access error occurs
