我在尝试重新创建以下查询时遇到问题：
select *
from acme_opties_relaties as r
inner join acme_options as o on o.id = r.id_a
inner join acme_option_subgroup as osg on osg.option_id = o.id
where osg.subgroup_id in (309, 303, 306, 300)
and o.id <> 47086
and r.soort = 2
and o.project_id = 140018
我得到的是以下查询：
SELECT t0_.id_a AS id_a_17, t0_.id_b AS id_b_18,
t0_.soort AS soort_0, t1_.id AS id_1, t1_.external_id AS external_id_2, t1_.external_ref AS external_ref_3, t1_.`name`
AS name_4, t1_.name_sales AS name_sales_5, t1_.price AS price_6, t1_.warranty AS warranty_7, t1_.material AS material_8, t1_.no_option
AS no_option_9, t1_.print AS print_10, t1_.text_warranty AS text_warranty_11, t1_.text_technical AS text_technical_12, t1_.text_sales AS text_sales_13, t1_.`group`
AS group_14, t1_.created AS created_15, t1_.updated AS updated_16, t1_.project_id AS project_id_19
FROM acme_opties_relaties t0_
INNER JOIN acme_options t1_ ON
(t1_.id <> 47086 AND t0_.soort = 2 AND EXISTS
(SELECT 1 FROM acme_option_subgroup t2_ INNER JOIN acme_subgroep t3_ ON t2_.subgroup_id = t3_.id WHERE t2_.option_id = t1_.id AND t3_.id IN (309, 303, 306, 300))
AND t1_.project_id = 140018)
任何指针/方向都会受到赞赏。

问题是关系和选项之间的连接不在r.option.id_a = option.id上，而是在r.option.id_a＆lt;＆gt;上。 X，它应该加入id并在应用＆lt;＆gt;的地方加入X
答案 0 :(得分：0)
哦，我们仍然可以使用大部分SQL。所以改成了：
private function getQuery(Option $option, SubElement $subElement, Type $type, string $direction, bool $inversed): Query
{
$direction = strtolower($direction);
$this->validateDirection($direction);
$query = 'select r, option, relation
from Acme\Domain\Entity\Option\Relation r
join r.option option
join r.relation relation
join option.subGroups osg
where osg in (:subGroup)
and option.project = :project
and r.type = :type
';
$query = $this->addDirectionWhere($query, $direction, $inversed);
$subGroups = iterator_to_array($subElement->getElement()->getSubGroups());
$q = $this->_em->createQuery($query);
$q->setParameter(':type', $type->getValue())
->setParameter(':option', $option->getId())
->setParameter(':project', $option->getProject())
->setParameter(':subGroup', $subGroups);
return $q;
}
我仍然非常愿意知道QueryBuilder中的等价物。因为这有我的偏好。
