我有三个实体,它们彼此有关系:

实体 1:

/** @ORM\OneToMany(targetEntity="ArticleOrderReference", mappedBy="purchaseOrder") */
protected $purchaseOrders;

实体 2:

/** @ORM\ManyToOne(targetEntity="PurchaseOrder", inversedBy="purchaseOrders") */
protected $purchaseOrder;

 /** @ORM\OneToMany(targetEntity="AOSupplierReference", mappedBy="articleOrderReference") 
 *  @ORM\OrderBy({"supplier" = "ASC"})
 * */
protected $articleOrderReferences;

实体 3:

/** @ORM\ManyToOne(targetEntity="ArticleOrderReference", inversedBy="articleOrderReferences")
 *  
 */
protected $articleOrderReference;

/** @ORM\ManyToOne(targetEntity="Supplier", inversedBy="suppliers") */
protected $supplier;

我的目标是创建一个这样的查询:

$order = $this->getDoctrine()->getManager()->createQuery("
        SELECT o, a , s
        FROM AcmeAppBundle:PurchaseOrder o
        JOIN o.purchaseOrders a
        JOIN a.articleOrderReferences s
        WHERE o.id = :orderId
          AND s.supplier = :supplierId
          AND s.amount > 0      
       ")
                   ->setParameter('orderId', $orderId)
                   ->setParameter('supplierId', $supplierId)
                   ->getOneOrNullResult();

但它显示此错误

Notice: Undefined index: supplier in /var/www/symfony/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/DefaultQuoteStrategy.php line 40 

,因为我@ORM\OrderBy({"supplier" = "ASC"})在Entity2中使用了。如果没有这个命令,它就可以工作。我不知道为什么它会引发未定义的索引错误。有什么想法可以解决这个问题吗?

我知道变量名选择不当。
