如何在 doctrine dql 中实现 intersect

Question

我正在寻找一种将相交函数 sql 实现到 doctrine dql 中以将其用于某些查询的方法。这是我想与他们的结果相交的查询：

$sql1 = "SELECT distinct o1 FROM  Application\Entity\Object1 o1 INNER JOIN Application\Entity\Object2 o2 WITH o2.fkObject1 = o1.pkObject1  WHERE o1.etat = 'valide' AND o2.pkObject2 = $id ";

$sql2 = "SELECT distinct o1 FROM  Application\Entity\Object1 o1 INNER JOIN Application\Entity\Object2 o2 WITH o2.fkObject1 = o1.pkObject1  WHERE o1.etat = 'attente' AND o2.pkObject2 = $id_2 ";

$sql = "sql1 INTERSECT $sql2 ";

// returns [语法错误] 第 0 行，第 556 列：错误：字符串预期结束，得到 'INTERSECT'

$query = $this->getEntityManager()->createQuery($sql);
$results = $query->getResult();

谢谢。

它对我有用的方式是像这样使用太多内部连接：

$sql =  "SELECT distinct o1 
         FROM  Application\Entity\Object1 o1 
         INNER JOIN Application\Entity\Object2 o2 WITH o2.fkObject1 = o1.pkObject1 
         INNER JOIN  Application\Entity\Object2 o3 WITH o3.fkObject1 = o1.pkObject1  
         WHERE o1.etat = 'valide' 
             AND o2.pkObject2 = $id 
             AND o1.etat = 'attente' 
             AND o3.pkObject3 = $id_2 ";

希望对您有所帮助。
