Thank You, the query suggested works but because of the primary index of
DOC_TESTA the value calculated of SALDO is not compliant with the result
of the rows of the query.
I solved by creating a stored procedure like this:
AS
BEGIN
SALDO = 0;
FOR SELECT
DT.DATA,
DT.DOCUMENTO_ID,
DT.NUMERO,
DT.SERIE,
DC.CARICO,
DC.SCARICO,
DC.CARICO - DC.SCARICO + :SALDO,
from
DOC_TESTA DT
JOIN DOC_CORPO DC on DT.ID = DC.DOC_TESTA_ID
WHERE
DC.ARTICOLO_ID = :ID
ORDER BY
DT.DATA,
DT.DOCUMENTO_ID,
DT.NUMERO,
DT.SERIE
INTO
:DATADOCUMENTO,
:DOCUMENTO_ID,
:NUMERO,
:SERIE,
:CARICO,
:SCARICO,
:SALDO,
DO SUSPEND;
END^
Thanks to all :)
