Hi Paul, How's going?
Maybe there are other criteria's that limits the result set to only return 24 rows? Richard Ji -----Original Message----- Sent: Thursday, August 29, 2002 11:53 AM To: Multiple recipients of list ORACLE-L I've been given a query to investigate. The performance varies extremely depending on whether the entire result set is fetched or a ROWNUM < n clause is attached; that makes sense to me. What doesn't make sense is the following: if we add WHERE ROWNUM < 50, the query returns 24 rows. If we add WHERE ROWNUM < 1000, the query returns 336 rows! I don't know the size of the entire result set (I'm running a count right now), but if the result set consists of at least 336 rows, shouldn't WHERE ROWNUM < 50 return 49 rows?
