How I can Iterate into SUM result from doctrine query - symfony

Question

I need some help about iterate over result in doctrine. This is my code for query:
$consulta = $em->createQuery('
SELECT bcr, SUM(bcr.volumenAlmacenado) as vol, SUM(bcr.pesoAlmacenado) as pes
FROM ResiduoBundle:BodegaContieneResiduo bcr
WHERE bcr.fechaIngreso BETWEEN :fechaP AND :fechaA AND bcr.fechaRetiro IS NULL
GROUP BY bcr.idResiduo
');
$consulta->setParameter('fechaA', $fechaActual);
$consulta->setParameter('fechaP', $fechaPasada);
return $consulta->getResult();
When I run in mysql return without problem. in symfony also get results. Now, when I tried to loop in twig I can't do, I think could be for my agregate functions in my query. I hope you can get me a clue or something about this. Grettings

Answer 1

You should added extension of mysql function SUM then you can use SUM function in doctrine query
another way you can direct execute your query or native query of doctrine
Try following query you can get result
$consulta = $em->executeQuery('SELECT bcr, SUM(bcr.volumenAlmacenado) as vol, SUM(bcr.pesoAlmacenado) as pes FROM ResiduoBundle:BodegaContieneResiduo bcr WHERE bcr.fechaIngreso BETWEEN :fechaP AND :fechaA AND bcr.fechaRetiro IS NULL GROUP BY bcr.idResiduo'),
array('fechaA'=> $fechaActual, 'fechaP' => $fechaPasada));
return $consulta->fetchAll();

You can also use native query of doctrine
use Doctrine\ORM\Query\ResultSetMapping;
$rsm = new ResultSetMapping();
$rsm->addEntityResult('ResiduoBundle:BodegaContieneResiduo', 'bcr');
$rsm->addFieldResult('bcr', 'idResiduo', 'idResiduo');
$rsm->addFieldResult('bcr', 'volumenAlmacenado', 'vol');
$rsm->addFieldResult('bcr', 'pesoAlmacenado', 'pes');
$sqlQuery = "SELECT bcr.idResiduo as idResiduo, SUM(bcr.volumenAlmacenado) as vol, SUM(bcr.pesoAlmacenado) as pes
FROM ResiduoBundle:BodegaContieneResiduo bcr
WHERE bcr.fechaIngreso BETWEEN :fechaP AND :fechaA
AND bcr.fechaRetiro IS NULL
GROUP BY bcr.idResiduo";
$query = $em->createNativeQuery($sqlQuery, $rsm)
->setParameter('fechaA', $fechaActual);
->setParameter('fechaP', $fechaPasada);
$query->getResult();
