Back to an SQL example, if I ask select employee_name, employee_age from employee I don't have to know the data type - unless the database is going to stuff it into a memory location for me. Then I would have to know, although the machinery might handle this for me. But the query might well return text, in which case I will get a string that represents the age value. Or I might be able to cast the age to a string within the query itself. So once again, it depends! Cheers, Tom Passin
