This is very similar to ticket #1480 (in fact I re-opened that ticket, but
was asked to create a new one).
Here's just my comments on the old ticket:
I'm seeing a similar issue as this ticket describes, but I think the
difference is that I'm using a m2m relationship for the subquery.
Users can have many Groups, and Groups can have many Users.
I want to list all of the groups that a user DOES NOT belong to:
{{{
Doctrine_Query::create()
->from('Group g')
->where('g.id NOT IN (SELECT g2.id FROM Group g2 INNER JOIN g2.Users u
WHERE u.id = ?', $user_id)
->execute();
}}}
Note, I had to use 'g2' in the subquery. If I use 'g' (like shown in the
manual) I get a "duplicate alias 'g'" exception thrown.
With soft delete enabled on both the User and Group objects (but not on
the refClass), Doctrine makes the following query:
{{{
SELECT g.id AS g__id, g.name AS g__name FROM groups g WHERE g.id NOT IN
(SELECT g2.id AS g2__id FROM groups g2 INNER JOIN groups_users g4 ON g2.id
= g4.group_id INNER JOIN users g3 ON g3.id = g4.user_id WHERE g3.id = ?
AND g.deleted = ? AND g2.deleted = ? AND g3.deleted = ?) AND g.deleted = ?
AND g2.deleted = ? AND g3.deleted = ?
}}}
Which causes the issue with there being too many tokens, and not enough
bound parameters.
If I disable soft delete on both of the objects in question, I get the
following query:
{{{
SELECT g.id AS g__id, g.name AS g__name FROM groups g WHERE g.id NOT IN
(SELECT g2.id AS g2__id FROM groups g2 INNER JOIN groups_users g4 ON g2.id
= g4.group_id INNER JOIN users g3 ON g3.id = c4.user_id WHERE g3.id = ?)
}}}
Which works fantastically. ;)
Using Doctrine revision 5067 (1.0 branch). PHP 5.2.5.
