sql - Doctrine2 使用 setParameters

Question

当我似乎在查询中使用参数时，出现错误

Invalid parameter number: number of bound variables does not match number of tokens

这是我的代码

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;
}

如何正确配置参数数组？

Answer 1

您没有在查询中包含您的参数。

$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);
