如何在没有关系表的情况下使用两个实体之间的QueryBuilder在Symfony Doctrine中加入

我有一个与实体类别相关的实体视频,我需要使用Doctrine QueryBuilder运行此SQL,我可以在所有视频中获得最常用的类别(1000+):

    SELECT c.*
    FROM Video v
    INNER JOIN video_category vc ON vc.video_id = v.id
    INNER JOIN Category c ON vc.category_id = c.id
    GROUP BY c.id
    HAVING COUNT(v.id) > 1000
    ORDER BY c.name ASC;

我的查询器:

    $queryBuilder = $this->getEntityManager()
        ->createQueryBuilder()
        ->select('c')
        ->from('AcmeVideoBundle:Video', 'v')
        // Can Doctrine join itself silently with relational info in the Entities?
        ->join('AcmeCategoryBundle:Category', 'c', Expr\Join::WITH, 'v.id = c.id')
        ->groupBy('c.id')
        ->having('COUNT(v.id) > 1000')
        ->orderBy('c.name', 'ASC')
        ->getQuery();

但是queryBuilder输出的SQL查询是这样的:

    SELECT c0_.id AS id0, c0_.NAME AS name1 
    FROM Video v1_ 
    INNER JOIN Category c0_ ON (v1_.id = c0_.id) 
    GROUP BY c0_.id 
    HAVING COUNT(v1_.id) > 1000
    ORDER BY c0_.NAME ASC

没有关系表(video_category)

实体映射:

    /**
     * Video
     *
     * @ORM\Table
     * @ORM\Entity(repositoryClass="Acme\VideoBundle\Entity\VideoRepository")
     */
    class Video
    {
        /**
         * @ORM\Id
         * @ORM\Column(type="integer")
         * @ORM\GeneratedValue(strategy="AUTO")
         */
        private $id;

        /**
         * @ORM\ManyToMany(targetEntity="Acme\CategoryBundle\Entity\Category", cascade={"persist"})
         */
        private $category;

        // More fields, getters and setters etc...
    }

    /**
     * Category
     *
     * @ORM\Table
     * @ORM\Entity(repositoryClass="Acme\CategoryBundle\Entity\CategoryRepository")
     */
    class Category
    {
        /**
         * @ORM\Id
         * @ORM\Column(type="integer")
         * @ORM\GeneratedValue(strategy="AUTO")
         */
        private $id;

        /**
         * @ORM\Column(type="string", length=255)
         */
        private $name;

        // More fields, getters and setters etc...
    }

如何使用关系表来使用doctrine Querybuilder运行原始SQL查询？我错过了什么？

信息:当我发现{field},persist,flush,clear,所有实体工作正常,Doctrine关系没问题,我有一个Video,Category和video_category表,原始SQL查询工作正常.
