Symfony 4, Doctrine Innerjoin doesn't use junction table
I have two entities (entity1 and entity2) in a ManyToMany relation. All tables are working fine, if i just need the object from one entity.
The fields in the entities are marked as ManyToMany including the mappedBy and reversedBy attributes.
I now need a subset from entity1 based on a where clause on entity2.
In SQL it's simple.
select
a.field1,a.field2
from entity1 as a
left join entity1_entity2 as b on a.entity1_id=b.foreignKey1
left join entity2 as c on b.foreignKey2=c.entity2_id
where c.whereField = 'value'
and a.whereField = 'anotherValue'
I want to use the Repository from entity1 and tried the query by the createQueryBuilder.
$query = $this->createQueryBuilder('e1')
->distinct(true)
->innerJoin(Entity2::class, 'e2')
->where("e2.whereField2= :whereE2")
->andWhere('e1.whereField1= :whereE1')
->setParameter("whereE2", $whereE2)
->setParameter("whereE1", $whereE1);
The result looks like a full outer join. The dump of the DQL/SQL seems that no junction table is used. Why?

You donn' have to specify the Entity in the innerJoin clause. Doctrine can do it by itself and use the join table too.
For example, entity1 as a ManyToMany annotation on the secondEntities property.
The queryBuilder may look like:
$query = $this->createQueryBuilder('e1')
->distinct(true)
->innerJoin('e1.secondEntities', 'e2')
->andWhere('e1.whereField1= :whereE1') // You can add additionnal conditions ;)
->setParameter("whereE1", $whereE1)
;
Note: You can use ON join condition like: ->innerJoin('e1.secondEntities', 'e2', Join::WITH, 'CONDITION HERE')
