right. since you only want the 30 latest posts, scanning 12k topics is absurd. i guess just ordering by (topic.update_date DESC, post_creationdate DESC) would allow the server to stop searching as soon as it has the required 30 posts. just be sure to have an index on topic.update_date the second choice, linking the post to the forum would let the server to do the scan based on post, not on topic, likely eliminating the need for the temporary table -- Javier -- You received this message because you are subscribed to the Google Groups "Django users" group.
