Hi List, Is there a way though which I can found out the column name causing an ORA-01438? I tried tracing the session, unfortunately, the trace file doesn't have any cluses about the column causing this error. Any link or workaround is appreciated. -- Best Regards, Syed Jaffar Hussain Oracle ACE 8i,9i & 10g OCP DBA http://jaffardba.blogspot.com/ http://www.oracle.com/technology/community/oracle_ace/ace1.html#hussain ---------------------------------------------------------------------------------- "Winners don't do different things.
