MessageIs that something new in 9i? I don't have it in 8.1.7.

As far as I can tell, the Explain Plan is 100% reliable. It shows how the query would execute if it was run from that session at that momement in time.

If you want to see how a query in the SGA actually ran, query the Oracle9i v$sql_plan view.
