当我似乎在我的查询中使用参数时,我收到一个错误
参数号无效:绑定变量数与令牌数不匹配

public function GetGeneralRatingWithUserRights($user, $thread_array)
{
$parameters = array(
'thread' => $thread_array['thread'],
'type' => '%'.$thread_array['type'].'%'
);
$dql = 'SELECT p.type,AVG(p.value)
FROM TrackerMembersBundle:Rating p
GROUP BY p.thread,p.type';
$query = $this->em->createQuery($dql)
->setParameters($parameters);
$ratings = $query->execute();
return $ratings;
}
