Question

我在symfony上使用这个原生SQL查询（这是一个非常糟糕的做法），但是我很难让它在没有触发多个错误的情况下使用DQL运行。

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();
    }

出于某种原因抛出此错误

错误：预期的Doctrine \ ORM \ Query \ Lexer :: T_WITH，“开启”

这是可行的查询

$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

如果您将ON更改为WITH，您的查询就可以了你也可以尝试

$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();

Answer 2

另外，如果Image Entity类中的Image模型和ImageVoters模型之间存在关系，您可以这样做：

->leftJoin('p.imageVoters', 'v')

学说将为你做其余的事。
