Thank You for your response but I can't do: sum(SALDO) because SALDO is
not a field of my table.

I badly explained myself: I have a table with only this fields:

DATA DOCUMENTO_ID NUMERO SERIE CARICO SCARICO


I need add SALDO fields in the result of the query to get a progressive
sum of CARICO - SCARICO.

Thanks
