使用setParameters的Doctrine2

您没有在查询中包含参数。

$parameters = array(    'thread' => $thread_array['thread'],     'type' => '%'.$thread_array['type'].'%');$dql = 'SELECt p.type,AVG(p.value)     FROM TrackerMembersBundle:Rating p     WHERe p.thread=:thread     AND type LIKE :type     GROUP BY p.thread,p.type';$query = $this->em->createQuery($dql)    ->setParameters($parameters);
