原則查詢聯接子查詢語法

Question

我一直在嘗試將以下原始sql傳輸到dql中，但四個小時都無法執行，您能幫我嗎？ 該查詢在數據庫中找到重復的哈希並給我訂單ID

SELECT h.order_id
FROM `Hash` h
INNER JOIN (SELECT `order_id`,hash
FROM `Hash`
GROUP BY `hash`
HAVING COUNT(*)  > 1
) dt ON h.hash=dt.hash ;

現在我的dql：

    SELECT h FROM PaymentBundle:Hash h 
JOIN
 (SELECT h1.order, h1.hash FROM PaymentBundle:Hash h1 GROUP BY h1.hash HAVING COUNT(h1)  > 1) 
dt WITH h.hash = dt.hash

但是h1.order提供語法錯誤，以及其他所有操作：

  [Semantical Error] line 0, col 40 near '(SELECT h1.hash': Error: Class '(' is not defined.  

我嘗試將其作為子查詢：

$subDql = 'SELECT h1 FROM PaymentBundle:Hash h1 GROUP BY h1.hash HAVING COUNT(h1)  > 1';
$subQuery = $this->getEntityManager()
 ->createQuery($subDql);

$dql = 'SELECT h FROM PaymentBundle:Hash h JOIN ('.$subQuery->getDQL().') dt ON h.hash = dt.hash';
$query = $this->getEntityManager()
  ->createQuery($dql);
return $query->getResult();

它給了我：

[學說\\ ORM \\查詢\\ QueryException]
[語義錯誤]第0行，行40位於'（SELECT h1 FROM'附近：錯誤：未定義類'（'。

[學說\\ ORM \\查詢\\ QueryException]
從PaymentBundle：Hash中選擇h加入（從PaymentBundle：Hash中選擇h1按h1.hash分組COUNT（h1）> 1）dt ON h.hash = dt.hash

Answer 1

我的解決方案：

$rsm = new ResultSetMappingBuilder($this->getEntityManager());
        $rsm->addRootEntityFromClassMetadata('PaymentBundle:Hash', 'h');

        $qb = $this->getEntityManager()->createNativeQuery("
               SELECT h.id, h.order_id
FROM `Hash` as h
INNER JOIN (SELECT `order_id`,hash
FROM `Hash`
GROUP BY `hash`
HAVING COUNT(*)  > 1
) dt ON h.hash = dt.hash
                 ", $rsm);
        return $qb->getResult();
