Symfony2 Doctrine Subquery

标签： php mysql symfony doctrine-orm doctrine

我尝试用queryBuilder()在symfony2中编写此查询，但我收到语法错误[Syntax Error] line 0, col 58: Error: Expected end of string, got 'SELECT' 

SELECT  * FROM  upload_video as p ORDER BY (SELECT  COUNT(*) FROM vote as v WHERE v.video_id = p.id ) DESC;

所以任何人都可以帮助我将此查询转换为Symfony2教义格式 $qb->createQuery("SELECT p FROM HotelPlanBundle:UploadVideo as p ORDER BY (SELECT COUNT(v) FROM HotelPlanBundle:Vote v WHERE v.video_id = p.id ) desc");

这是UploadVideo实体

我正在尝试做的是尝试根据投票表或集合中的投票来订购视频。

答案 0 :(得分：0)

您可以使用QueryBuilder来实现这一目标：

$qb = $em->createQueryBuilder();
$result = $qb->select('uv, COUNT(v) AS HIDDEN votesCount')
    ->from('HotelPlanBundle\Entity\UploadVideo', 'uv')
    ->leftJoin('uv.votes', 'v')
    ->where('v.videoId = uv.id')
    ->orderBy('votesCount', 'DESC')
    ->groupBy('uv')
    ->getQuery()
    ->getResult();

或者如果您想使用DQL：

$em->createQuery('SELECT uv, COUNT(v) as AS HIDDEN votesCount FROM HotelPlanBundle\Entity\UploadVideo uv LEFT JOIN uv.votes v WHERE v.videoId = uv.id GROUP BY uv ORDER BY votesCount DESC');
