我正在使用学说为电子商务网站建立运输系统。为此，我根据结账时的产品和地区数据获得了相应的运输方式和价格。
我在QueryBuilder中使用以下代码：
$shippingPriceReccords
= $this->em->createQueryBuilder()
->select('price')
->from('OrderShippingPrice', 'price')
->innerJoin('OrderShippingMethod', 'method', 'price.fkOrderShippingMethod = method.id')
->innerJoin('OrderShippingMethodRegionMapping', 'map', 'map.fkOrderShippingMethod = method.id')
->where('price.fkProductType = :fkProductType')
->andwhere('price.fkBrand = :fkBrand')
->andwhere('map.fkRegion = :fkRegion')
->setParameters([
'fkProductType' => $fkProductType,
'fkBrand' => $fkBrand,
'fkRegion' => $regionID,
])
->getQuery()
->setFetchMode("OrderCart", "address", \Doctrine\ORM\Mapping\ClassMetadata::FETCH_EAGER)
->getResult();
但这是失败的并且给了我这个错误：
[Syntax Error] line 0, col 87: Error: Expected Literal, got 'JOIN'
以上查询中的DQL：
SELECT price FROM OrderShippingPrice price INNER JOIN OrderShippingMethod method INNER JOIN OrderShippingMethodRegionMapping map WHERE price.fkProductType = :fkProductType AND price.fkBrand = :fkBrand AND map.fkRegion = :fkRegion

有人能告诉我我做错了什么吗？谢谢你的帮助。
答案 0 :(得分：1)
您在innerJoin方法调用中缺少一个参数。你必须这样做：
$shippingPriceReccords
= $this->em->createQueryBuilder()
->select('price')
->from('OrderShippingPrice', 'price')
->innerJoin('OrderShippingMethod', 'method', 'WITH', 'price.fkOrderShippingMethod = method.id')
->innerJoin('OrderShippingMethodRegionMapping', 'map', 'WITH', 'map.fkOrderShippingMethod = method.id')
->where('price.fkProductType = :fkProductType')
->andwhere('price.fkBrand = :fkBrand')
->andwhere('map.fkRegion = :fkRegion')
->setParameters([
'fkProductType' => $fkProductType,
'fkBrand' => $fkBrand,
'fkRegion' => $regionID,
])
->getQuery()
->setFetchMode("OrderCart", "address", \Doctrine\ORM\Mapping\ClassMetadata::FETCH_EAGER)
->getResult();
请参阅documentation：
// Example - $qb->innerJoin('u.Group', 'g', Expr\Join::WITH, $qb->expr()->eq('u.status_id', '?1'))
// Example - $qb->innerJoin('u.Group', 'g', 'WITH', 'u.status = ?1')
// Example - $qb->innerJoin('u.Group', 'g', 'WITH', 'u.status = ?1', 'g.id')
public function innerJoin($join, $alias, $conditionType = null, $condition = null, $indexBy = null);
