Hello TDM Community,
I have another issue with keys in a table. Let us asume I have table A in a database. That table got a key already, the primary key. Now I want to add another key to table A, it is a unique column. When I look to the sql code, it will create a unique constraint and thats what I want a unique constraint, not a unique index. But why this key got the property NOT NULL be default and why I cannotchange that ? (maybe it is possible but cannot see how).
