I have been going through the SQL reference guide looking for some help on
restricting the values that can be entered into a table. I would like to
put this constraint on the file from within the DDL is possible.....so far
I have been unable to figure it out.
Example: I have a 1A field that can only have a value of 'C', 'V' or 'U',
no other values will be allowed.....is there a way to include this within
the DDL?
