Good Day everyone, I have a small doubt about using tkprof with explain parameter. Say, when we use, set autot trac exp for any insert,update,delete that command is executed and produces the execution plan. Whereas if I use explain plan for insert,update,delete commands, it only gives the execution plan without actually executing the command. I have set instance level tracing with trace leve 1, and wants to caputre all the statements. However, my question is, when I am using tkprof with explain parameter, if there are any insert,update or delete statements in my trace file, are they going execute or just produces explain plan wihtout executing them? --=20 Best Regards, Jaffar, OCP DBA Banque Saudi Fransi Saudi Arabia ---------------------------------------------------------------------------= ------------- "It is your atittude, not your aptitude that determins your altitude." -- //www.freelists.org/webpage/oracle-l
