我正在尝试使用Doctrine QueryBuilder执行以下SQL查询:
DELETE php FROM product_hole_pattern php
INNER JOIN hole_pattern hp ON php.hole_pattern_id = hp.id
INNER JOIN hole_pattern_type hpt ON hp.hole_pattern_type_id = hpt.id
WHERE php.product_id = 4 AND hpt.slug='universal';
我有这个
$qb = $this->entityManager->createQueryBuilder();
$query = $qb->delete('\SANUS\Entity\ProductHolePattern', 'php')
->innerJoin('php.holePattern', 'hp')
->innerJoin('hp.holePatternType', 'hpt')
->where('hpt.slug = :slug AND php.product=:product')
->setParameter('slug','universal')
->setParameter('product',$this->id)
->getQuery();
但我得到:
[Semantical Error] line 0, col 50 near 'hpt.slug = :slug': Error: 'hpt' is not defined.
附带错误信息的DQL为:
DELETE \SANUS\Entity\ProductHolePattern php
WHERE hpt.slug = :slug AND php.product=:product
所以这些连接似乎被完全省略了。
