Is there any way you can specify that the only permissible values (is it called a domain?) that can be entered in varchar2 field in an Oracle table to, for example, A, B and C?
We can restrict what values users can enter at the application level, but it would be nice to be able to also restrict what can be entered at the database level, in case other means of entering data are ever used or if the application layer fails, for whatever reason, to trap an unwanted value.
