An application I'm developing (postgres back end) has a SQL DOMAIN as a
check constraint on state/province codes. This is different from the SA
ORM's domain perspective. The SQL statement is:
CREATE DOMAIN the_state_code AS char(2)
DEFAULT '??'
CONSTRAINT valid_state_code
CHECK (value IN ('AL', 'AK', 'AZ', ...));
and in postgres tables is this attribute:
state_code char(2),
which is in the equivalent model classes; e.g.,
org_state = Column(String)
My question is how I add the CREATE DOMAIN DDL in models.py. I am not seeing
the answer in the SA docs.
TIA,
Rich
