Not directly. You can do this in an AFTER UPDATE or AFTER INSERT trigger if the table has a primary key. You get the key value from the SYS_NEW cursor, and then issue an UPDATE statement against the table. I assume (but don't know for sure) that this would also fire the UDPATE trigger, so you have to be careful not to get caught in an infinite loop (the trigger must only issue the UDPATE under certain conditions, and the UDPATE you issue should not fulfill those conditions). -- Larry
