using a foreign key in MySQL

[digitalslavery]

can anyone point me twards a tutorial that describes how to link child tables with the master table for MySQL, like how can i keep a userID linked to child tables for my project. I am trying to figure out how to establish referential integrity for MySQL, unless it only exists for MS Access. Thanks!

Foreign key support is not availible on the default myISAM table in MySQL. I think INNODB supports FKs and referrential integrity.
