I want to limit the number of records that a user can input in a specific table. for instance, users should be able to subscribe to a race which are limited to 10 tracks.
I would i to have a clause or something that might help my to prevent users from exceeding the number of tracks available for the race and while the 10th competitor subscribes. no over competitor will be able to subscribe to this race.
I hope to be clear about my request and that someone will be able to help me.
Thanking you beforehand
