RE: SQL Result Count Question..

Careful. In the case of a select (which I assume you're using since you
mention a resultset) the number of rows is a guess and nothing more. CPUs
count, query parallelism, and order by clauses should all have an effect on
the guess. In an action query (update, delete, etc) the rowcount is
accurate, but not in a select. I'd look at count(*) if that fits your needs.
