hi there,
with two tables i want to make some constraint-restrictions
create table address ( id serial, country_id int4, ....);
and
create table country (id serial, ...);
to make sure that now country-row is deleted if there is still a country_id
in address table.
e.g.
address: 1, 2, ...
country: 2, ...
now country wouldn't be allowed to be deleted.
how to do that?
thanks fo help
olaf
