Robert - I always try EXPLAIN PLAN as a starting point.

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
