mapping – 具有多个joinColumns的Doctrine 2 ManyToOne

在适用于给定productId的普通SQL中：

SELECT pi.*,pis.* FROM product_item pi
LEFT JOIN product_item_sortorder pis
    ON pi.productId = pis.productId
    AND pi.toolboxItemId = pis.toolboxItemId
WHERE pi.productId = 6

我为它写了DQL如下：

$this->_em->createQuery(
    'SELECT pi
    FROM EntitiesProductItem pi
    LEFT JOIN pi.sequence s
    WHERE pi.product = ?1'
);

如果输出$query-> getSQL(),我会得到以下SQL：

SELECT p0_.id AS id0,p0_.productId AS productId1,p0_.priceGroupId AS priceGroupId2,p0_.toolboxItemId AS toolboxItemId3,p0_.levelId AS levelId4,p0_.parentId AS parentId5,p0_.productId AS productId6,p0_.toolboxItemId AS toolboxItemId7 FROM product_item p0_ LEFT JOIN product_item_sortorder p1_ ON p0_.productId = p1_. AND p0_.toolboxItemId = p1_. WHERE p0_.productId = ? ORDER BY p0_.id ASC

如您所见,找不到referencedColumnNames：

LEFT JOIN product_item_sortorder p1_ ON p0_.productId = p1_. AND p0_.toolboxItemId = p1_.

 */
class ProductItemSortorder
{
    ...

    /**

     * @JoinColumn(name="toolboxItemId",referencedColumnName="id")
     */
    protected $toolboxItem;

    ...
