Subject values null in summation of record
Author Ismael L. Donis Garcia
I use FB 2.5.1

When I hold a consultation of a filter-tipped board he returns a record with void value to me. As I avoid this?

select sum(t.saldo) as saldo from table1 t where

returns 1 record with value null

As I make in order that do not return records in this case?

Best Regards
