Doctrine2 Multiple Join works with createQuery but not with queryBuilder - php

Question

If I'm using querying without queryBuilder with this dql
$query = $this->_em
->createQuery("SELECT p, g, c
FROM LikeYeah\GoBundle\Entity\Product p
JOIN p.garments g
LEFT JOIN g.colours c
ORDER BY p.id DESC
");
everything is fine, but if I use the (what I belive is the same) query trough query builder like this
$qb->select('p, g, c')
->from('LikeYeah\GoBundle\Entity\Product', 'p')
->join('p.garments', 'g')
->leftJoin('g.colours', 'c')
->orderBy('p.id', 'desc');
I get the following error:
"Semantical Error] line 0, col 66 near '.colours c, LikeYeah\GoBundle\Entity\Product': Error: Identification Variable g used in join path expression but was not defined before."
What am I missing?

Answer 1

Try this: using addSelect after your joins:
$qb->select('p')
->join('p.garments', 'g')
->addSelect('g')
->from('LikeYeah\GoBundle\Entity\Product', 'p')
->join('p.garments', 'g')
->leftJoin('g.colours', 'c')
->addSelect('c')
->orderBy('p.id', 'desc');

You can help from this method
public function findSampleClothingTypeGender($gender) {
$query = $this->getEntityManager()
->createQuery('
SELECT p FROM Acme:Product p
JOIN p.clothing_type ct
WHERE p.gender = :gender'
)->setParameter('gender', $gender);
try {
return $query->getResult();
} catch (\Doctrine\ORM\NoResultException $e) {
return null;
}
}

Answer 3

Try with below one
$qb->select('p','g','c')
->from(array('LikeYeah\GoBundle\Entity\Product','p'))
->join(array('p.garments','g'))
->join(array('g.colours','c'),'LEFT')
->order_by('p.id','DESC');

Answer 4

may be try
$qb->select('p, g, c')
->from('GoBundle:Product', 'p')
->join('p.garments', 'g')
->leftJoin('g.colours', 'c')
->orderBy('p.id', 'desc');
show your $qb init and DQL result

Answer 5

It works for me.
$this->_em->createQueryBuilder()
->select('fu,e,t')
->from('\xxxx\AdminBundle\Entity\FrontUser','fu')
->join('fu.read_essays','e')
->leftJoin('e.tags','t')
->getQuery()->execute();
I think you should create a new QueryBuilder object.
You can use follow code to see Dql of that QueryBuilder
$qb->getDQL();
