Symfony2的学说子查询

Question

我试着写在Symfony2的这个查询与queryBuilder()，但我得到一个语法错误[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; 

因此，谁能帮我转换这个查询成Symfony2的学说格式 $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

我想要做的是我试图根据投票表中或集合中的投票来排序视频。

Answer 1

您可以使用QueryBuilder以实现：

$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(); 

，或者如果你想使用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');
