【问题描述】：

如何像这样在 LEFT JOIN 中添加 AND SELECT * FROM photo LEFT JOIN like_photo lp on photo.id = lp.photo_id AND lp.user_id = 6 WHERE photo.is_public = 1？

`{`
    `return $this->createQueryBuilder('photo')`
        `->leftJoin("photo.likedPhotos", "lp", "photo.id = lp.Photo")`
        `->addSelect('lp')`
        `->where('photo.is_public = 1')`
        `->orderBy('photo.uploaded_at', 'DESC')`
        `->getQuery();`

}

在 lp 表上使用 WHERE user_id = 6 后我需要离开联接

尝试：

return $this->createQueryBuilder('photo')
        ->leftJoin("photo.likedPhotos", "lp", Join::WITH, "photo.id = lp.Photo AND lp.user_id = 6")
        ->addSelect('lp')
        ->where('photo.is_public = 1')
        ->orderBy('photo.uploaded_at', 'DESC')
        ->getQuery();
