Cake can generate query for static array, but what aobut query from query as in example: select * from users where group_id in (select group_id from users where id=$u1). Or even query from quyry from query? For example look on this query: SELECT name FROM group WHERE gid IN ( SELECT gid FROM group_member WHERE uid=u1 AND gid IN (SELECT gid FROM group_member WHERE uid=u2)) How to generate such query by cake? You may said that cake can join tables for us, but query from query possible will more effictive on oracle for example or join will not allowed on Facebook :) Really facebook main reason to create such solution Yes, you right.

$this->User->findAll(array(‘group_id’ => $this->User->field(‘group_id’, array(‘id’ => $u1))));

FYI, IN query are implemented in Cake:
$this->Users->findAll(array(‘group_id’ => array(1, 2, 3)));
will query:
SELECT *
FROM users
WHERE group_id IN (1, 2, 3);
