Well, I was trying to select rows from one table if there are no rows in another table.

My original query was:

SELECT * FROM `jos_datsogallery` as a WHERE a.published = 1 
and a.approved=1 NOT EXISTS (SELECT * FROM `jos_datsogallery_votes`
As v WHERE v.vip=62 AND v.vpic=a.id) ORDER BY a.imgdate DESC

but it keeps failing.

I made some testing and shortened my query to:

SELECT * FROM `jos_datsogallery` WHERE EXISTS (SELECT 1)

Which is supposed to select everything from jos_datsogallery as ‘EXISTS (SELECT 1)’ is always true.

I tried phpMyAdmin:

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 ‘EXISTS (SELECT 1) LIMIT 0, 30’
at line 1

What’s wrong?

MySQL version: 4.0.27

MySQL doc: http://dev.mysql.com/doc/refman/4.1/en/exists-and-not-exists-subqueries.html

    EXISTS is only supported in 4.1 and above – the documentation you linked is a combined documentation for both 4.0/4.1 so it may be misleading as to what versions actually support the keyword.

    Since you updated your question to state that you’re using 4.0.x that would be why it’s not working for you.
