If you don't want to query the database again, you could always write the results to a file. There's a matter of cleaning up old cache files though, but that's not what was asked... ;D

Doesn't sound right to me... for starters, 3000 records / 30 per page = 100 pages... it seems unlikely that every user will make it through the 100 pages, so they (or the server) would be carrying around useless data. What you want to do is limit each query to 30 results on each page, using MySQL's LIMIT. SELECT FROM table WHERE something ORDER BY id LIMIT 0,30 (first page) SELECT FROM table WHERE something ORDER BY id LIMIT 30,60 (2nd page) etc. Justin French on 04/06/02 3:06 AM, Jay Blanchard ([EMAIL PROTECTED]) wrote: > Howdy! > > I am working on a project where approximately 3k - 5k records are returned > and need to be displayed 30 per page with 'previous' and 'next' navigation > at the request of the users.
