Question

I would like to write nested query with Doctrine; Sample SQL is like below:

SELECT * FROM layer WHERE layer.id NOT IN 
               (SELECT task_id FROM users_tasks WHERE user_id = 1) 
AND parent_id IS NOT NULL AND leaf IS TRUE

I have problem converting the SECOND SELECT statement.

Thanks in advance.

I would like to make it with createQueryBuilder not createQuery.

try this :

1) create your subquery

$subquery = $this->_em->createQueryBuilder()
    ->select('t.id')
    ->from('yourBundle:Task', 't')
    ->innerjoin('t.user','u')
    ->where('u.id = 1')
    ->getDQL();

2) after create your query

$query = $this->_em->createQueryBuilder();
$query->select('l')
      ->from('yourBundle:Layer', 'l')
      ->where($query->expr()->notIn('l.id', $subquery))
      ....;

I tested it and it works 🙂
