oracle ora-00979 symfony2 doctrine2 - sql

Question

I'm building the following DQL:
SELECT partial operador.{id, pmn, neteo},
sum(outcollect.montoTotal) as montoOut,
outcollect.periodo as periodo,
outcollect.pagado
FROM RoamingOperadoresBundle:Operador operador
LEFT JOIN operador.operadorHub operadorHub
LEFT JOIN operador.outcollect outcollect
WHERE operador.ishub = 0
AND operador.neteo = 1
AND operador.incluirReportes = 1
AND operador.pmn not in('CHLTM', 'CHLCM')
AND operador.id not in(SELECT op.id
FROM RoamingOperadoresBundle:Operador op
LEFT JOIN op.operadorHub opHub
LEFT JOIN op.outcollect out
WHERE (opHub.desde <= out.periodo and (opHub.hasta >= out.periodo or opHub.hasta is null))
)
AND operador.activo = 1
GROUP BY operador.pmn, outcollect.periodo ORDER BY operador.pmn
Which transforms into this SQL:
SELECT o0_.id AS ID0,
o0_.pmn AS PMN1,
o0_.neteo AS NETEO2,
sum(o1_.monto_total) AS SCLR3,
o1_.periodo AS PERIODO4,
o1_.pagado AS PAGADO5
FROM operador o0_
LEFT JOIN operador_hub o2_ ON o0_.id = o2_.operador_id
LEFT JOIN outcollect o1_ ON o0_.id = o1_.operador_id
WHERE o0_.ishub = 0
AND o0_.neteo = 1
AND o0_.incluirReportes = 1
AND o0_.pmn NOT IN ('CHLTM', 'CHLCM')
AND o0_.id NOT IN (SELECT o3_.id FROM operador o3_ LEFT JOIN operador_hub o4_ ON o3_.id = o4_.operador_id LEFT JOIN outcollect o5_ ON o3_.id = o5_.operador_id WHERE (o4_.desde <= o5_.periodo AND (o4_.hasta >= o5_.periodo OR o4_.hasta IS NULL)))
AND o0_.activo = 1
GROUP BY o0_.pmn, o1_.periodo
ORDER BY o0_.pmn ASC
Which gives the following error:
ORA-00979: no es una expresión GROUP BY
Any pointers on how to change the DQL to solve this problem?
I'm using doctrine2, symfony2 and OCI8

Answer 1

Per Oracle documentation
ORA-00979 not a GROUP BY expression
Cause: The GROUP BY clause does not contain all the expressions in the SELECT clause. SELECT expressions that are not included in a group
function, such as AVG, COUNT, MAX, MIN, SUM, STDDEV, or VARIANCE, must
be listed in the GROUP BY clause.
Action: Include in the GROUP BY clause all SELECT expressions that
are not group function arguments.
So you need to include all the expressions/column in select list to your group by. change the group by of your SQL query to below
group by o0_.pmn, o1_.periodo, o0_.neteo, o1_.pagado, o0_.id
GROUP BY of DQL to
GROUP BY operador.pmn, outcollect.periodo, operador.id,
operador.neteo, outcollect.pagado
