How to implement ON ( ... OR ...) mysql query in doctrine2 queryBuilder - mysql

Question

I have a SQL query in MYSQL:
For example
SELECT s.* FROM vplanning.cities as c1
INNER JOIN vplanning.cities as c2
ON (c1.id = c2.area_id)
INNER JOIN vplanning.storages as s
ON (s.city_id = c2.id OR s.city_id = c1.id)
WHERE c1.id = 109;
In doctrine I can write something like this (from my work code):
$query = $em->getRepository('VplanningPageBundle:Storage')
->createQueryBuilder('s')
->innerJoin('s.city', 'c1')
->innerJoin('c1.area', 'c2')
->innerJoin('s.storagestype', 'st')
->where('c2.id = :cityID')
->andWhere('st.typename = :storagesTypeName')
->andWhere('s.active = :active')
->setParameters(array(
'cityID' => $cityID,
'storagesTypeName' => $storagesTypeName,
'active' => 1
))
->orderBy('s.adress')
->getQuery();
As you can see, I show my relation in
->innerJoin('s.city', 'c1')
but I need also relation like
->innerJoin('s.city', 'c2')
with this condition:
ON (s.city_id = c2.id OR s.city_id = c1.id)
But it throws this error:
Error: 'c2' is already defined
c1 and c2 are the same entity and have a inner relation.

Answer 1

Try this:
$repository = $em->getRepository('VplanningPageBundle:Storage');
$qb = $repository->createQueryBuilder('storage');
//We can now use the expr()
$qb->join('storage.city', 'city', Join::WITH)
->join('city.area', 'area', Join::WITH, $qb->expr()->eq('area.id', ':cityID'))
->join('storage.storagestype', 'type', Join::WITH, $qb->expr()->eq('type.typename', ':storagesTypeName'))
->where('storage.active = :active')
->setParameters(array(
'cityID' => $cityID,
'storagesTypeName' => $storagesTypeName,
'active' => 1
))
->orderBy('storage.adress');
$query = $qb->getQuery();

Answer 2

Try smth like this
$qb = $this->getRepository('VplanningPageBundle:City')->createQueryBuilder('c');
$qb->leftJoin('c.area', 'a')
->join('c.storage', 's', Join::ON, $qb->expr()->orX($qb->expr()->eq('c.id', 's.id'), $qb->expr()->eq('a.id', 's.id')))
->innerJoin('s.storagestype', 'st')
->where('c.id = :cityID')
->andWhere('st.typename = :storagesTypeName')
->andWhere('s.active = :active')
->setParameters(array(
'cityID' => $cityID,
'storagesTypeName' => $storagesTypeName,
'active' => 1,
))
->orderBy('s.adress')
->getQuery()
;

The solution of the problem was very difficult as for me, I have to study it :)
This is a answer for my question from some forum board:
$qb = $em->getRepository('VplanningPageBundle:Storage')->createQueryBuilder('storage');
$query = $qb->join('storage.city', 'city1', Join::WITH)
->leftJoin('city1.area', 'area', Join::WITH, $qb->expr()->eq('area.id', ':cityID'))
->leftJoin('storage.city', 'city2', Join::WITH, $qb->expr()->eq('city2.id', ':cityID'))
->join('storage.storagestype', 'type', Join::WITH, $qb->expr()->eq('type.typename', ':storagesTypeName'))
->where('storage.active = :active')
->andWhere($qb->expr()->orX($qb->expr()->isNotNull('city2'), $qb->expr()->isNotNull('area')))
->setParameters(array(
'cityID' => $cityID,
'storagesTypeName' => $storagesTypeName,
'active' => 1
))
->orderBy('storage.adress')
->getQuery();
