sql - 如何将此 SQL 查询转换为 Doctrine 查询

Question

我在 symfony 上使用这个 native SQL 查询(这是一个非常糟糕的做法)，但我正在努力让它与 DQL 一起运行而不触发几个错误。

SELECT Image.path, Image.name 
FROM Image
LEFT JOIN ImageVoters ON Image.id = ImageVoters.image_id
WHERE ImageVoters.voter_id =1
AND ImageVoters.action =  'favourite'
ORDER BY Image.created_at ASC

这就是我到目前为止所得到的

    public function findMyFavourites()
    {
       return $this->getEntityManager()
       ->createQuery('SELECT p.path,p.name 
       FROM GabrielUploadBundle:Image p 
       LEFT JOIN GabrielUploadBundle:ImageVoters v 
       ON p.id  = v.image_id 
       WHERE v.action ="favourite" 
       ORDER BY p.created_at ASC')
       ->getResult();
    }

由于某种原因抛出此错误

Error: Expected Doctrine\ORM\Query\Lexer::T_WITH, got 'ON'

这是有效的查询

$em = $this->getDoctrine()->getManager();
$query = $em->getRepository('GabrielUploadBundle:Image')->createQueryBuilder('p')
    ->select(array('p.path', 'p.name','p.id','p.upvotes','p.imageowner','p.createdAt','p.updatedAt'))
    ->leftJoin('GabrielUploadBundle:ImageVoters', 'v', 'WITH', 'p.id = v.image_id')
    ->where("v.action = 'favourite'")
    ->andWhere("v.voter_id = 1")
    ->orderBy('p.createdAt', 'ASC')
    ->getQuery();

Answer 1

如果将 ON 更改为 WITH，您的查询就可以了。
您也可以尝试

$query = $em->getRepository('GabrielUploadBundle:Image')->createQueryBuilder('p')
   ->select(array('p.path', 'p.image'))
   ->leftJoin('GabrielUploadBundle:ImageVoters', 'v', 'WITH', 'p.id = v.image_id')
   ->where("v.action = 'favourite'")
   ->orderBy('p.createdAt', 'ASC')
   ->getQuery();
$result = $query->getResult();
