really noob question here. i have this experimental database design:
create table products (
product_id serial primary key,
description text,
supplier_id????) ;
create table supplier (
supplier_id serial primary key,
description text) ;
the products table should be linked to the supplier table via "supplier_id" column. i can't find out what would be the data type of supplier_id in table products to do that. i tried
supplier_id serial primary key references supplier
