If the query is too big you can get this error :

SQL Error: 1153: Got a packet bigger than 'max_allowed_packet' bytes

My query is :

SELECT `User`.`id` FROM `users` AS `User` WHERE `User`.`id` NOT IN (1,2,3,4,5.....

 

I have testing this query on my sql server and I get the previuos error if I have 70000 'id' in NOT IN conditions.

I can't modify max_allowed_packet  in my production server

I think that it isn't the best solutions

Hi

I'm newbie with cakephp

I have model User, model Group and model UsersGroup ( an user can belongs to many groups and a group can have many users).

I would ask how in CakePHP can I find all users that not belong to the Group group_id (where group_id is a generic int value)

Many thanks
