Hm...
First thought...If i understood right...
Try using INNODB type of table in MySQL.....
hope this helps.....

wish I knew the answer to this one...
I believe foreign key constriants work with innodb tables but myisam tables
are the default.
I'm working on a project in which I really need to enforce referential
integrity but I'm not sure how to assault the learning curve on the innodb
setup, if innodb support is even possible at all through my web/database
hosting service.

The recent 4.xx release of mysql supports fkey and ref integrity from within
innodb tables which are natively supported (no special installatin stuff
necessary). Here's an example of a schema I'm working on for swim meet
volunteers. Note that once workers exist for a particular timeslot, the
slot cannot be deleted (leaving orphans) nor can workers be assigned to
nonexistant slots.
