That's certainly a possibility Raj.....but I like to think about these things a 
bit and see if I can't think my way through to a solution.  Too often, assuming 
Oracle screwed up (and they certainly do, fairly regularly) can lead to errors 
or misunderstandings.

Hmm...hadn't thought of that.  I did some quick poking around, and a quick 
IxOra reference.  That seems to be absolutely true.

I did find a few counterexamples, though, I think.  If LOADS is hard parses and 
PARSE_CALLS is total parses, then why do I have rows
in V$SQL where LOADS > PARSE_CALLS?

Any thoughts, Tanel?  (Or anyone else?)

Hmm....a slightly closer look at those SQLs, and they all seem to be recursive 
SQL.  Not sure what's going on there.
