Question

I have two tables users and assets and foreign key is user_id. I want users detail and count of each user’s asset So, I wrote query as below but not getting records. Please help me.

$users = $this->select()
             ->from(array('u' => 'users'),
                    array('firstname'))
             ->joinLeft(array('a' => 'assets'),
                    'u.id = a.user_id',
                    array('asset_per_user' => 'COUNT(a.id)'))
             ->group('u.id');        

Answer 1

‘Select query cannot join with another table ‘

That mean $this is quite certainly a Zend_Db_Table in your example. By default select taken from a Zend_Db_Table cannot perform joins (as they are used for Active Record operation by default).

Add:

$users->setIntegrityCheck(false);

And this merror essage will disappears. I’ve not checked the SQL query yet, it’s maybe right.
