Method Details

absolute

public boolean absolute(int row)
            throws 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().

Returns:
true if the cursor is on the result set; false otherwise

getCursorName

public String getCursorName()
            throws SQLException
Gets 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 the 'for update' clause 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.

Returns:
the SQL name for this ResultSet object's cursor

Returns the XSQLVAR structure for the specified column.

insertRow

public void insertRow()
            throws SQLException
Inserts the contents of the insert row into this ResultSet objaect and into the database. The cursor must be on the insert row when this method is called.
Since:
1.2

isAfterLast

public boolean isAfterLast()
            throws SQLException
Indicates whether the cursor is after the last row in this ResultSet object.
Returns:
true if the cursor is after the last row; false if the cursor is at any other position or the result set contains no rows
Since:
1.2

isBeforeFirst

public boolean isBeforeFirst()
            throws SQLException
Indicates whether the cursor is before the first row in this ResultSet object.
Returns:
true if the cursor is before the first row; false if the cursor is at any other position or the result set contains no rows
Since:
1.2

isFirst

public boolean isFirst()
            throws SQLException
Indicates whether the cursor is on the first row of this ResultSet object.
Returns:
true if the cursor is on the first row; false otherwise
Since:
1.2

isLast

public boolean isLast()
            throws SQLException
Indicates 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.
Returns:
true if the cursor is on the last row; false otherwise
Since:
1.2

last

public boolean last()
            throws SQLException
Moves the cursor to the last row in this ResultSet object.
Returns:
true if the cursor is on a valid row; false if there are no rows in the result set
Since:
1.2

moveToCurrentRow

public void moveToCurrentRow()
            throws SQLException
Moves the cursor to the remembered cursor position, usually the current row. This method has no effect if the cursor is not on the insert row.
Since:
1.2

moveToInsertRow

public void moveToInsertRow()
            throws 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 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. An updateXXX method must be called before a getXXX method can be called on a column value.
Since:
1.2

next

public boolean next()
            throws 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.

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

previous

public boolean previous()
            throws SQLException
Moves the cursor to the previous row in this ResultSet object.

Note: Calling the method previous() is not the same as calling the method relative(-1) because it makes sense to callprevious() when there is no current row.

Returns:
true if the cursor is on a valid row; false if it is off the result set
Since:
1.2

refreshRow

public void refreshRow()
            throws 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 updateXXX 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.

Since:
1.2

relative

public boolean relative(int rows)
            throws 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 different from calling the method next() because 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.

Returns:
true if the cursor is on a row; false otherwise
Since:
1.2

rowChanged

public void rowChanged(org.firebirdsql.jdbc.FBFetcher fetcher,
                       byte[][] newRow)

Specified by:
rowChanged in interface FBObjectListener.FetcherListener
Parameters:
fetcher - instance of FBFetcher that caused this event.
newRow - new row.

rowDeleted

public boolean rowDeleted()
            throws SQLException
Indicates whether a 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 this ResultSet object can detect deletions.
Returns:
true if a row was deleted and deletions are detected; false otherwise
Since:
1.2

rowInserted

public boolean rowInserted()
            throws SQLException
Indicates whether the current row has had an insertion. The value returned depends on whether or not this ResultSet object can detect visible inserts.
Returns:
true if a row has had an insertion and insertions are detected; false otherwise
Since:
1.2

rowUpdated

public boolean rowUpdated()
            throws SQLException
Indicates whether the current row has been updated. The value returned depends on whether or not the result set can detect updates.
Returns:
true if the row has been visibly updated by the owner or another, and updates are detected
Since:
1.2

setFetchDirection

public void setFetchDirection(int direction)
            throws 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.
Since:
1.2
See Also:
What Is in the JDBC 2.0 API, Statement.setFetchDirection

setFetchSize

public void setFetchSize(int rows)
            throws 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.
Parameters:
rows - the number of rows to fetch
Since:
1.2
