Jonathan, Thanks for you explaination of what you ment by "forced code path". I took it to mean the use of outlines to "control" the flow through Oracle. Ron ROR mª¿ªm
>>> [EMAIL PROTECTED] 04/18/02 01:23PM >>> It doesn't mean anything exciting or exotic, I was just trying to express the idea that sometimes Oracle will execute one piece of (internal) code because of an init.ora parameter, hint, visible set of table statistics etc. rather than taking another path which you might typically expect it to take.
