Doctrine resultsetmapping should return array

Question

I have this query:

select count(*) as total_count, sum(total) as total_value, status from invoice group by status;

when I execute it in the database I get the following:

I want to achieve the same using Doctrine2 but the following code only returns one row:

$rsm = new ResultSetMapping();
$rsm->addScalarResult('total_count', 'totalCount');
$rsm->addScalarResult('total_value', 'totalValue');
$rsm->addScalarResult('status', 'status');

$query = $this->getObjectManager()->createNativeQuery('
  select count(*) as total_count, sum(total) as total_value, status from invoice group by status', $rsm);

$result = $query->getResult();

return $result;

This is the result of the above:

array (size=1)
  0 => 
    array (size=3)
      'totalCount' => string '1432' (length=1)
      'totalValue' => string '55447.80999999999' (length=2)
      'status' => string 'paid' (length=4)

Answer 1

You should use:

$result = $query->getScalarResult();

Instead of :

$result = $query->getResult();

Hope this help

Answer 2

Because you are using getResult doctrine will try to fetch all matching rows for you. You need to use Doctrine's getSingleResult if you don't want the result to be an array of arrays.

So for you simply:

$result = $query->getSingleResult();

You can also limit the number of results to throw a QueryException if more or none are returned:

$query->setMaxResults(1);
