Pergunta
Usually when I need an ID for a database table, I just declare it as UNSIGNED INT, but what is the maximum value for this kind of ID? How can I know it? I'm using mysql server, but i think it would be useful to get an answer for all platforms. If I'm doing wrong, what kind of id should be used instead?
