Not "that's what I've heard", but "that's what I think", isn't it? But it realy doesn't matter if you "think" or if you "have heard", my point was very clear: If you only realy give it a second thought it is more than self-evident that number of records can only be gotten from database blocks themself! Oracle can make no trics there... And no need for any "reliable URLs" to prove that ;).
