SQL descriptor

Hi everybody, We are using 7.22 on Sun. Our development team ran into a problem. They use ESQL/C and try to create a dynamic SQL routine for the rest of our team. The problem is about a descriptor that return from our SQL statement. It does not contain a table name, only field name and its value are present. In some case we need to make a query that request for a the same field name from different table. We try to use an alias name for that kind of field, but its too complicated. Is there anybody out there have any suggestion for me? Will future version solve this problem? Thanks a lot, Siripa
