Re: "NOT NULL"

If your RAD (I don't know what this means at all) does not allow the
keyword "DEFAULT" you might probably use this:

INSERT INTO some_table (second_field_name, third_field_name) VALUES
(second_field_value, third_field_value);

If you not mention first_field_name in the first parenthesis, the
default value will be used.

The reference for INSERT can give you further syntax details:
