I am tryng to execute this query (working on Postgres) but can't get it working with doctrine ORM :(
SELECT r.descrizione, SUM(c.peso) as totale
INNER JOIN inforifiuti AS r ON r.codicerifiuto = c.tiporifiuto AND r.idcomune = c.idcomune
WHERE c.idcomune = :id_comune AND c.dataora >= '2019-01-01' AND c.dataora <= '2019-10-30'
GROUP BY c.tiporifiuto, r.descrizione
Querybuilder
$query = $qb
->select(array('r.descrizione','SUM(c.peso) as totale'))
->innerJoin('c.tiporifiuto','r', Expr\Join::WITH, $qb->expr()->andX(
$qb->expr()->eq('c.tiporifiuto', 'r.codicerifiuto'),
$qb->expr()->eq('c.idcomune', 'r.idcomune')
))
->where('c.idcomune = :id_comune')
->andWhere($qb->expr()->between('c.dataora', ':date_from', ':date_to'))
->setParameter('id_comune', $id_comune)
->setParameter('date_from', $date_from, \Doctrine\DBAL\Types\Type::DATETIME)
->setParameter('date_to', $date_to, \Doctrine\DBAL\Types\Type::DATETIME)
->groupBy('c.tiporifiuto')
->addGroupBy('r.descrizione')
->getQuery();
I get this error
A single-valued association path expression to an entity with a composite primary key is not supported. Explicitly name the components of the composite primary key in the query.
tryed to replace ->GroupBy with but same error
->add('groupBy', new Expr\GroupBy(['c.tiporifiuto', 'r.descrizione']))
UPDATE
Tryed using direct DQL but same identical error
$query = $this->getEntityManager()->createQuery(
'SELECT r.descrizione, SUM(c.peso) as totale
FROM App\Entity\conferimenti AS c
INNER JOIN App\Entity\inforifiuti AS r
WHERE c.idcomune = :id_comune AND c.dataora >= :date_from AND c.dataora <= :date_to
GROUP BY c.tiporifiuto, r.descrizione')
->setParameter('id_comune', $id_comune)
->setParameter('date_from', $date_from, \Doctrine\DBAL\Types\Type::DATETIME)
->setParameter('date_to', $date_to, \Doctrine\DBAL\Types\Type::DATETIME);

Answer 1

try this:
$this->manager->createQuery('SELECT .........');
like this example :
$query = $entityManager->createQuery(
'SELECT p
FROM AppBundle:Product p
WHERE p.price > :price
ORDER BY p.price ASC'
)->setParameter('price', 19.99);
