我想從product_item表中選擇基於productId和toolboxItemId的product_item_sortorder表中的匹配行。Doctrine 2 ManyToOne with multiple joinColumns
在正常的SQL,這將是對於給定的產品編號:
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
我寫的DQL它如下:
$this->_em->createQuery(
'SELECT pi
FROM Entities\ProductItem pi
LEFT JOIN pi.sequence s
WHERE pi.product = ?1'
);
然後我得到下面的SQL如果我輸出的$查詢 - > getSQL():
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
正如你可以看到referencedColumnNames都沒有發現:
012在product_item表個LEFT JOIN product_item_sortorder p1_ ON p0_.productId = p1_. AND p0_.toolboxItemId = p1_.

ProductItem實體
<?php
/**

* @Table(name="product_item")
*/
class ProductItem
{
...
/**
* @ManyToOne(targetEntity="ProductItemSortorder")
* @JoinColumns({
* @JoinColumn(name="productId", referencedColumnName="productId"),

protected $sequence;
...
?>
ProductItemSortOrder實體
<?php
/**

class ProductItemSortorder
{
...
/**

*/
protected $product;
/**

*/
protected $toolboxItem;
...
}
?>
我更新了一點問題位和下面你可以看到我想執行哪個查詢 – tom 2011-04-12 10:15:40
