Robert,
I will make the assumption that you are on a newer version of Oracle.
If I remember correctly, a view does not use an index and will use a
full table scan. That could be the cause for the time difference.
I know that this doesn't answer your question but it might trigger
other thoughts that solve the problem.

I'm fighting a view.... Someone hand me a big dagger with which to kill
it.
I have a view that takes 6 minutes to run when I query it like this:
select
count(*) from TST_XVW a
where claim_carrier_key=41721;
Yet, if I take the SQL from the view, add the claim_carrier_key
predicate to
it, I get a run time of 6 seconds. I've tried several different hints
(push_pred, use_nl, etc) and I'm just not seeming to be able to get
the
optimizer to give me a good plan. Any help on this would be
appreciated.
Robert
