But wouldn't that show up in the plan? I must be missing something.
How can you tell by examining the predicate section where the filtering is

Even if the plan hash values are the same, go still ahead and compare the
predicate sections of the good vs bad child cursors.
Predicate existence (or placement) is not part of the plan hash value - so
how early you're filtering the rows may differ.

I have a couple of SQL statements that have multiple child cursors. Each
child cursor has the same plan hash value. The plans all show "this is an
adaptive plan (rows marked '-' are inactive)". The difference is that on
the "good" child cursor, the plan also shows "statistics feedback used for
this statement". Since all of the plans have the same plan hash value, I
can not use baselines (or can I).
Any suggestions on how to force Oracle to always use the "good" child
