No, the code worked because the code (as well as the exmple data) is more restrictive than the data-definition. You can define the n-m table as 

mysql> create table user_role (
    -> user_id int(11) not null default '0',
    -> role_id int(11) not null default '0',
    -> primary key (user_id, role_id),
    -> foreign key user_fk (user_id) references user (id),
    -> foreign key role_fk (role_id) references role (id) 
    -> );

the data fits, the program works, and the Class::DBI definition actualy meets the data-definition as close as possible (AFAI understand it at a quick glance), but given the example-data, nothing really changed. If the data-definition allows for more than the program actualy does, thats undesirable and bad style and a big problem in the future, but not a problem now.

may well be that I don't understand you at all, I'm really tired and the finer points of english conversation escape me all the time....
