不相同的条件不起作用Symfony2

Question

I try to create custom finder in Repository class. And the where condition is find posts what created not by current user. But I still geting all posts. Here is the code:

public function selectRelatedTrips($assoc, $profileId)
{

    $params = array();
    $query = $this
        ->getEntityManager()
        ->createQueryBuilder()
        ->select('t')
        ->from('VputiTripBundle:Trip', 't')
        ->where('t.profile != :profile');
    $params['profile']=$profileId;
    foreach ($assoc as $k => $v) {
        $query->orWhere('t.startCity = :param' . $k);
        $query->orWhere('t.targetCity = :param' . $k);
        $params['param' . $k] = $v;
    }

    return $query->setParameters($params)
        ->setMaxResults(20)
        ->orderBy('t.id', 'desc')
        ->getQuery()
        ->getResult();
}

What I am doing wrong?

If t.profile is an entity, you should compare like this:

->where('IDENTITY(t.profile) != :profile');
