How can resultset records be restricted to certain rows?
With a 2.0 driver, you can use the setFetchSize() method within a Statement or a ResultSet object.
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.
