With a 2.0 driver, you can use the setFetchSize() method within a Statement or a ResultSet object. For example, Statement stmt = con.createStatement(); stmt.setFetchSize(400); ResultSet rs = stmt.executeQuery(“select * from customers”); will change the default fetch size to 400. You can also control the direction in which the rows are processed. For instance: stmt.setFetchDirection(ResultSet.FETCH_REVERSE) will process the rows from bottom up. The driver manager usually defaults to the most efficient fetch size…so you may try experimenting with different value for optimal performance.
