Subj:   Re: How to retrieve tablename and its count dynamically
 
From:   McCall, Glenn David

Interesting - do you mean union or union all?

There is a difference. Essentially, the union all does not perform a duplicate row check. Although, for the size of the returned result set, you wouldn't *imagine* it would make a huge difference in performance.

Of course reality isn't always what might be expected!
