Re:Subject: multiple tables and amounts

Would this work better ? SELECT comments.id, comments.phid, COUNT(comments.id) AS comments, COUNT(ratings.id) AS ratings FROM photos LEFT OUTER JOIN comments ON photos.id=comments.phid LEFT OUTER JOIN ratings ON photos.id=ratings.phid WHERE photos.id=1 GROUP BY comments.id, comments.phid (You cannot GROUP BY count values btw as you probably realise) I'm not clear where creating a temporary table gets you ;-) Cheers - Neil.

CREATE TEMPORARY TABLE comments_temp SELECT comments.id, comments.phid, COUNT(comments.id) AS ratings FROM comments LEFT JOIN ratings ON ratings.phid=comments.phid WHERE comments.phid=1 GROUP BY comments.phid, comments.id;
