Question

我正在尝试修改DQL以组合两个不同的结果：

class ContentRepository extends EntityRepository
{
    /**
     * @param string $userId
     * @return array
     */
    public function findOwnerReadByUserId(string $userId): array
    {
        $qb = $this->createQueryBuilder('c');
        $qb->select('c')
            ->innerJoin('c.reactions', 'rea', Join::WITH, $qb->expr()->eq('rea.content', 'c.id'))
            ->where('c.userId = :userId')
            ->orderBy('rea.createdAt', 'DESC')
            ->setParameters(['userId' => $userId]);

        return $qb->getQuery()->getResult();
    }

    /**
     * @param string $userId
     * @return array
     */
    public function findOtherReadByUserId(string $userId): array
    {
        $qb = $this->createQueryBuilder('c');
        $qb->select('c')
            ->innerJoin('c.receivers', 'rec', Join::WITH, $qb->expr()->eq('rec.userId', ':userId'))
            ->innerJoin('c.reactions', 'rea', Join::WITH, $qb->expr()->eq('rea.content', 'c.id'))
            ->where('rec.read = :read')
            ->orderBy('rea.createdAt', 'DESC')
            ->setParameters(['userId' => $userId, 'read' => true]);

        return $qb->getQuery()->getResult();
    }
}

这两个查询都像魅力一样工作但我想避免使用array_merge因为顺序而来。检索这两个结果的任何建议都会产生一个DQL？

感谢@AlexBlex

这就是答案：

    /**
     * @param string $userId
     * @return array
     */
    public function findNotPendingByUserId(string $userId): array
    {
        $dql = <<<DQL
  SELECT DISTINCT c
  FROM ApiBundle:Content c
  INNER JOIN c.receivers rec 
  INNER JOIN c.reactions rea
  WHERE (rec.read = true AND (c.userId = :userId OR rec.userId = :userId))
  ORDER BY rea.createdAt DESC
DQL;

        return $this->getEntityManager()
            ->createQuery($dql)
            ->setParameters(['userId' => $userId])
            ->getResult();
    }

结合两个不同的DQL
