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.


Thanks
