Can you use an Inline Query in mysql?

I am not sure if it is even possible and I can't find any documentation on it or make it work...

Hope you can help!!

SELECT c.NAME catname,
            t.ID id,
            t.title,
            u.USERNAME username,
            DATE_FORMAT(t.date,'%d/%m/%Y %h:%i%p') date,
            p.p_date
FROM category c,
         topics t,
         users u,
         (SELECT max(date) p_date
                    , topic_id p_topic_id
          FROM post
          GROUP BY topic_id) p
WHERE t.cat_id = c.ID
AND t.USERID = u.ID
AND p.p_topic_id = t.id
ORDER BY t.date DESC


Is there an equivalent if you cannot do it this way?

I get the following error.


MySQL said:


#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 'SELECT max( date ) p_date, topic_id p_topic_id
FROM post
GROUP



This would work in Oracle... Unfortuantely I am not an expert in MYSQL

if you have mysql version > 5.0 perhaps your query works. for all other versions :

SELECT c.NAME AS catname,
            t.ID AS id,
            t.title,
            u.USERNAME AS username,
            DATE_FORMAT(t.date,'%d/%m/%Y %h:%i%p') AS date,
            MAX(p.date) AS p_date
FROM category AS c INNER JOIN topics AS t ON c.ID = t.cat_id
                              INNER JOIN users AS u ON t.USERID = u.ID
                              INNER JOIN post AS p ON p.topic_id = t.id
GROUP BY t.topic_id
ORDER BY t.date DESC
