Basically I'm just unsure as to why this query is failing to execute:
(SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username
FROM (replies) AS a
INNER JOIN members ON replies.reply_by = members.id)
UNION
(SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username
FROM (posts) as b
WHERE posts.post_set = 0
INNER JOIN members ON posts.post_by = members.id)
ORDER BY d DESC LIMIT 5
I'm getting this error:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use
near 'a INNER JOIN members ON replies.re' at line 2
All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works?
Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message.
(The two queries on there own work fine)
