Sorry, but this is wrong. I aways do that on my SPs and it works perfectly.

He is saying he wants ALL records when passing a null param *OR* only
records where some field match the param otherwise.

>> where FIELD = :param or :param is null

How exactlty are you executing this? Is it inside some SP or Trigger??
