I am going to upgrade my database from version 4 to 5. However I found some of my web application doesn't work on MySQL5
e.g following statement works in 4 but not 5 SELECT f.*, c.id as cat_id, c.position as cat_position, c.state as cat_state, c.name as cat_name, c.description as cat_desc, c.image, c.url, m.member_name as mod_name, m.member_id as mod_id, m.is_group, m.group_id, m.group_name, m.mid FROM ibf_forums f, ibf_categories c LEFT JOIN ibf_moderators m ON (f.id=m.forum_id) WHERE c.id=f.category ORDER BY c.position, f.position Error: Unknown column 'f.id' in 'on clause' The alias seem not working? What should I do, I dont want to rewrite all my sql statement.... Thanks.
