Hmm.
% man "create type"
NAME
CREATE TYPE - define a new data type
SYNOPSIS
CREATE TYPE name AS
( attribute_name data_type [, ... ] )
CREATE TYPE name (
INPUT = input_function,
OUTPUT = output_function
[ , RECEIVE = receive_function ]
[ , SEND = send_function ]
[ , INTERNALLENGTH = { internallength | VARIABLE } ]
[ , PASSEDBYVALUE ]
[ , ALIGNMENT = alignment ]
[ , STORAGE = storage ]
[ , DEFAULT = default ]
[ , ELEMENT = element ]
[ , DELIMITER = delimiter ]
)
"input_function" and "output_function" sure _sound_ like what you're
looking for.
They would make your imagined issue of "missing leading zeros" go
away.
I think that CREATE TYPE has been around for a goodly few years now;
it is not impossible that this functionality has been around longer
than MS Access (which is saying something!).
