EchoFool Posted September 23, 2011 Share Posted September 23, 2011 Hey, I have a query which loads events and i want to order them by total number of fans of that event. The number of fans is based on how many people are a fan of the event which is stored in a secondary table for example: Event Table Event ID | Event Name Event Fans UserID | Event ID How do i do it ?

Maq Posted September 23, 2011 Share Posted September 23, 2011 Join the tables on EventID, SUM the UserID and ORDER BY the sum alias. Link to comment https://forums.phpfreaks.com/topic/247736-order-data-by-total-number-of-rows/#findComment-1272148 Share on other sites More sharing options...
EchoFool Posted September 23, 2011 Author Share Posted September 23, 2011 If i SUM won't that only create one row result similar to count? or is it : <?php SUM(t2.userid) AS totalfans FROM eventtable t1 LEFT JOIN eventfans t2 ON t1.eventid=t2.eventid ORDER BY totalfans ?> Link to comment https://forums.phpfreaks.com/topic/247736-order-data-by-total-number-of-rows/#findComment-1272151 Share on other sites More sharing options...
Maq Posted September 23, 2011 Share Posted September 23, 2011 Yeah sorry. Not sure if this is legal with joins, but try: SELECT COUNT(t2.userid) AS t, eventname, FROM eventtable t1 LEFT JOIN eventfans t2 ON t1.eventid=t2.eventid GROUP BY t2.eventid ORDER BY t Link to comment https://forums.phpfreaks.com/topic/247736-order-data-by-total-number-of-rows/#findComment-1272153 Share on other sites More sharing options...
