If a clear was a "delete from table" followed by a reorg I'd agree, but my understanding is that it's a special function where the database understands that ALL the rows are going to be toasted so indicies aren't maintained during the clear. -Walden ------------ Walden H Leverich III President Tech Software (516)627-3800 x11 WaldenL@TechSoftInc.com http://www.TechSoftInc.com -----Original Message----- From: email@example.com [mailto:firstname.lastname@example.org] Sent: Monday, January 07, 2002 15:12 To: email@example.com Subject: RE: sql - Drop and Add constraints Walden, It's always been my impression that as the data is cleared the access paths are maintained at that time. Thus if you have a bunch of them the clear takes longer. I'm not aware of any "access path invalidation" although I'm not as close to the system technically as I used to be. Maybe this has been improved over the last several releases, but it always seemed that the same file with and without related access paths cleared in much different amounts of time.
