MySQL do support composite keys . Have a look on the mysql database
structure the "columns_priv" table has 5 fields in its primary key.
I think you should use an auto_increment as your primary field instead.

Assunto: [PHP-DB] composite keys
> Hi all:
> I am using php4.0.3pl1 with MySQL 3.22.32 on Apache for RH Linux.

> I have a table/relation of sports, where amongst other categories, are
> teams, where there can be many 'teamNames' & 'teamInfos' for one sport.
>
> The problem here is that without the use of a composite key:
> 'sportName' & 'TeamName', there can be no method of uniquely
> identifiying a row or tuple. A smuch of the info for each sport is
> repeated.

> Does MySQL support the use of composite keys? I am using phpMyAdmin
