Jaguar Posted June 22, 2007 Share Posted June 22, 2007 I need to do soemthing like this. SELECT * FROM topics ORDER BY replies/date LIMIT 10; I want to get the top 10 "popular" topics from my forums. I define popular as the total number of replies divided by time elapsed since the topic was created. ---topics--- date (date) (date topic was posted) replies (mediumint) (total number of replies) ------------ Will I have to do math in PHP to get the number of days (or minutes or seconds) passed since the date? That could get bad if I actually ever get a lot of forums. Quote Link to comment Share on other sites More sharing options...

Jaguar Posted June 22, 2007 Author Share Posted June 22, 2007 Thank you very much! Exactly what I was looking for <3 If I did it in PHP the array could get huge. Quote Link to comment Share on other sites More sharing options...
