Hallo, The following query works fine but returns *all nulls* if no rows between :DaData and :AData
SELECT DEPOSITO_ID, RIPORTO, CARICO, SCARICO, RIPORTO + ESISTENZA AS ESISTENZA, IMPEGNATI, ORDINATI FROM ( SELECT DT.DEPOSITO_ID, (SELECT SUM(DC2.CARICO - DC2.SCARICO) FROM DOC_CORPO DC2, DOC_TESTA DT2 WHERE DC2.DOC_TESTA_ID = DT2.ID AND DC2.ARTICOLO_ID = :ID AND DT2.DATA < :DaData ) AS RIPORTO, SUM(DC.CARICO) as Carico, SUM(DC.SCARICO) as Scarico, SUM(DC.CARICO - DC.SCARICO) as ESISTENZA, SUM(DC.IMPEGNATI) as Impegnati, SUM(DC.ORDINATI) as Ordinati FROM DOC_CORPO DC, DOC_TESTA DT WHERE DC.DOC_TESTA_ID = DT.ID AND DC.ARTICOLO_ID = :ID AND DT.DATA >= :DaData AND DT.DATA <= :AData GROUP BY DT.DEPOSITO_ID ) How I can modify it?
