Sorry, Nightie, the "pipe dream" is the one that billows out of the pipes of you and the rest of the SQL Squadron.Do you think you might want to make a post that actually added something to the discussion. I seem to remember somebody being banned for spamming this very thread. How are your posts any different?
... et tu, Nightie. And in case you're not aware of it the paper posted by a_g covers that matter - and we've discussed it in the past (and you lost then, too).
Go study the paper more thoroughly.
