I'm trying to think of the ways I can accomplish having a master
database of countries and states/provinces that I can reference in
several other databases.
I'd like to have a table of countries available for selection by the
users in a web app, but I'm not sure of the best way to then allow them
to pick the state/province in which they reside in that country. I've
thought of a foreign key in the state table that references the parent
country and do a state/province lookup off of that (SELECT state FROM
tblStates JOIN ON tblState.countryID=WhatYouChoseAlready, or something
similar - my syntax may not be correct).
Is there another way that has been used by anyone with good success?
Any suggestions welcome.
And would ISO.org be the best place to find such country and province
lists, or perhaps the Postal Service? Any past experience?
