Hi, I am using tkprof with the following options: waits=yes sys=no explain=user1/user1 Still I can see lot of internal sql's as shown by last lines of tkprof output file: 7390 user SQL statements in trace file 88912 internal SQL statements in trace file. 3347 SQL statements in trace file. Which option do I need to use if I just want to see information about the user sql statement in the output file? Thanks --Harvinder -- //www.freelists.org/webpage/oracle-l
