Hallo, I need to write a query with a computed field that contain a progressive sum like this table:
DATA DOCUMENTO_ID NUMERO SERIE CARICO SCARICO SALDO 01/01 A 1 A 1 0 1 02/01 A 2 A 3 0 4 02/01 V 33 B 0 2 2 02/01 V 35 C 0 1 1 I need to modify this query by adding SALDO field to get progressive sum of CARICO - SCARICO: select DT.DATA, DT.DOCUMENTO_ID, DT.NUMERO, DT.SERIE, DC.CARICO, DC.SCARICO from DOC_TESTA DT JOIN DOC_CORPO DC on DT.ID = DC.DOC_TESTA_ID WHERE DC.ARTICOLO_ID = :ID ORDER BY DATA, DOCUMENTO_ID, NUMERO, SERIE How I do?
