How to select 3 topic and list the most recent comment
I been banging my head against the wall. I'm not entirely sure what i am doing wrong here...
I hope some SQL guru is out there and willing to help.
I have two tables. Discussion_Topic and Discussion_Comment.
There is a dtop_id value in the 'discussion_topic' table that matches a column in 'discussion_comment' called 'dcom_topic_id'. (that allows for selecting comments that belong to the topic with matching IDs. Pretty simple.)
I made a new column in discussion_topic called 'rank'. There will be 3max listed and they are labeled 1,2,3 and in that order too. So i can grab 3 topic titles and output them to the page. (not having a problem with this)
Next I want to grab the most recent comment from the comments table and output the comment just below each topic title. And Here lies the issue. The results always show the oldest comment.
Here is the SQL statement i am using:
SELECT * FROM discussion_topic, discussion_comment WHERE discussion_topic.dtop_id = discussion_comment.dcom_topic_id AND discussion_topic.rank > 0 AND discussion_topic.dtop_active = 1 GROUP BY discussion_topic.dtop_id ORDER BY discussion_topic.jtcrank ASC
thanks in advance!
