I have a question. I am doing the following UPDATE which 9 times out of 10 updates no rows due to the where clause. Performance wise, would I be better off doing a SELECT first to check if the record exists and then do the update???

UPDATE processed
SET flag = 'N', delete_dt = sysdate
WHERE emp_id = rec.emp_id
AND policy = rec.policy

Thanks in advance
Todd
