Okay, I'm lost. You're tossing around words like project, but you've got a field contid and parid, and I read this three times and I don't know which is which. What's a cont? What's a par? I assume Msg is short for message. Type them out. Your fingers may hurt today, but your brain will thank you tomorrow. :-) > The only way I could think to do this was to create a query that did a > SELECT COUNT(*) from tbl_content_messages using the IN operator with a > list > of all of the contid values associated with each project. I think you maybe want LEFT OUTER JOIN to keep the projects with 0 messages. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
