Hi there,

Currently I have the following domain defined:

CREATE DOMAIN IMPOEXPO AS
CHAR(1)
NOT NULL
CHECK (VALUE IN ('I','E'))

I want to add more check constraints to it, i.e. it should end up
being like this:

CREATE DOMAIN IMPOEXPO AS
CHAR(1)
NOT NULL
CHECK (VALUE IN ('I','E','1','2'))

How can I do this in FB 1.5.3?

Thanks a lot,

-Benton
