Pretty cool. :-) How did you measure this? Did you do (pseudo code): start_time = now SQL BEGIN SQL INSERT's.. ... SQL END end_time = now print number_inserts / (end_time - start_time) or SQL BEGIN start_time = now SQL INSERT's .... end_time = now SQL END print number_inserts / (end_time - start_time) This makes a difference, since a lot of processing is done on commit time. The second variant might thus be misleading. Maarten -- Maarten Boekhold, boekhold@tibco.com TIBCO Finance Technology Inc.
