Symfony2中的innerJoin查询

Question

我的mysql查询：

SELECT p.name, c.id 
FROM customer c  
INNER JOIN sales_order so ON so.customer_id=c.id  
INNER JOIN sales_order_item soi ON so.id=soi.sales_order_id  
INNER JOIN product p ON p.id=soi.product_id  WHERE c.id=49454\G;

这在MySql中有效，但是当此查询在doctrine2中转换时，出现错误

"[Semantical Error] line 0, col 87 near 'so ON so.customer_id=c.id': Error: Identification Variable sales_order used in join path expression but was not defined before."

我用symfony的形式写这个：

$builder
        ->add('filter', 'entity', array(
            'label' => 'Show',
            'class' => 'RocketBraPrintBundle:SalesOrderItem',
            'query_builder' => function($er) {
                return $er->createQueryBuilder('p','so','c','soi')
                          ->select('p.name','c.id')
                          ->from('customer','c')
                          ->innerJoin('sales_order','so','ON','so.customer_id=c.id')
                          ->innerJoin('sales_order_item','soi','ON','so.id=soi.sales_order_id')
                          ->innerJoin('product','p', 'ON', 'p.id=soi.product_id')
                          ->where('c.id=49454\G');
            },
            'empty_value' => 'All',
            'required' => false
        ))

谁能告诉我以symfony2方式转换此mysql查询的正确方法是什么？

Answer 1

->innerJoin('c.sales_order')

其中“ sales_order”是“客户”实体的确切关系名称。

Answer 2

这对我来说很复杂，因为我有点困惑，它的转换是这样的。

$er->createQueryBuilder('soi')
   ->select('soi','p','so')
   ->innerJoin('soi.salesOrder', 'so')
   ->innerJoin('soi.product', 'p')
   ->innerJoin('so.customer', 'c')
   ->groupBy('p.name')
   ->orderBy('p.name', 'ASC')
   ->where('so.customer = ' . $options['data']['customerid']);
