I define a table, Permits, that includes a column for type.

Permit_Type is a domain with permissible names:

CREATE DOMAIN Permit_Type
as TEXT
CHECK (value in ('Environmental', 'Health', 'Safety', 'Occupancy'));

Can I name that domain check within the Permits table as follows?

CREATE TABLE Permits (
...
type Permit_Type
CONSTRAINT invalid_permit_type
...
);

If not, does the constraint name belong in the domain definition?

Rich
