Symfony2 doctrine DQL不替换通配符

Question

我正在尝试从我的Symfony2项目中查询模型，但我无法将通配符替换为我的DQL查询。看;

$q2 = 
  'SELECT 
    p.codigo, 
    p.descripcion, 
    SUM(l.cantidad) as cantidad, 
    SUM(l.cantidad*l.pvp) as euros
  FROM 
    MGFAppBundle:LineaVenta l 
  JOIN 
    MGFAppBundle:Producto p 
  WITH
    l.producto = p.id
  JOIN 
    l.venta v
  WITH
    l.venta = v.id
  WHERE 
    l.producto IN (:array) 
  AND 
    v.farmacia = :farmacia 
  GROUP BY 
    p.codigo';
$query2 = $this->em->createQuery($q2)
  ->setParameter('farmacia', $farmacia)->setParameter('array', $array);
$porFarmacia = $query2->getResult();
// This does not return a single value, when it should return 2 lines.

echo $query2->getSQL();
// Returns:
// SELECT p0_.codigo AS codigo0, p0_.descripcion AS descripcion1, SUM(l1_.cantidad) AS sclr2, SUM(l1_.cantidad * l1_.pvp) AS sclr3 FROM LineaVenta l1_ INNER JOIN Producto p0_ ON (l1_.lineaventas_id = p0_.id) INNER JOIN Venta v2_ ON l1_.venta_id = v2_.id AND (l1_.venta_id = v2_.id) WHERE l1_.lineaventas_id IN (?) AND v2_.farmacia_id = ? GROUP BY p0_.codigo

所以，问号应该是参数。任何提示？提前谢谢。
