Maybe, I have tested with MySQL 5.1.37

Are each of the both subselects working?

Or anybody know the difference between that versions, and can help?

Thanks.

Subqueries cannot be used in MySQL 4.

Thanks for that informationen.

Have anybody a better query?

Each of the subquery should work stand alone.

It's a facebook optimised version of MySQL

There's still some clusters with MySQL from memory...

Everywhere is now MySQL 5.1

SELECT *  FROM user_newtalk WHERE user_id IN ( SELECT n.user_id FROM ( user_newtalk n JOIN user u ON u.user_id = n.user_id ) LEFT JOIN page p ON u.user_name = p.page_title AND p.page_namespace =3 WHERE p.page_title IS NULL  ) OR user_ip IN ( SELECT n.user_ip FROM user_newtalk n LEFT JOIN page p ON n.user_ip = p.page_title AND p.page_namespace =3 WHERE p.page_title IS NULL  AND n.user_id =0 );

PAGE makes it unhappy

means a sql error or a long query run time? Feel free to make the query better or split it in two queries (one for users and one for anons)
