I still think it's more effecient to use two queries in your case. One with a COUNT(*) to get total records, and one with a LIMIT to just get the 40 you want. With a smaller table, it may not matter, but with large tables, you could be using up a lot of resources by selecting everything, but then only using 40 rows of it. You already have the connection open, so two efficient queries would still be quick. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
