As for returning PK, regular "INSERT" has "RETURNING" clause, but I don't see one for "insert" used withing "MERGE".

If you've read more carefully what the problem is you'd see that MERGE can't work because it works on one table upserting another. I have one table being inserted from 6 tables. Thanks genius.

What is the best way of doing it ( simplest ) ? Regards, Ranko. Ranko, "Simplest way" is to solicit opinions without using a search engine or checking the documentation. Its also usually "simplest" to leverage the existing provided functionality, rather than writing your own routines, error handling, etc. A search of "oracle 10.1 upsert" in google.com + "I'm feeling lucky" produced this for me. Perhaps you might get lucky too. Paul http://www.psoug.org/reference/merge.html MERGE INTO USING ON () WHEN MATCHED THEN WHEN NOT MATCHED THEN ; -- http://www.freelists.org/webpage/oracle-l
