Did you read the section of that manual page headed "Join processing
changes in MySQL 5.0.12"? It explains why and how to rewrite all such
queries using explicit JOIN ... ON | USING syntax.

Hi,
Take a look at the answer written by Peter Brawley to Jason Chan at Oct

Jason
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
Look up joins in the 5.0 or 5.1 manual. As of 5.0.12, MySQL implemented
ANSI/ISO compliance, breaking comma joins of the sort you use above. You
need explicit JOIN ... ON | USING syntax to remove referential
ambiguities.

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.
