Hi, Is the Primary Key Column mandatory?
Supposing: If I have two tables: Clients and Cars, and a third table Clients_R_Cars, that is a relationship between Clients and Cars. I only need to know what cars the clients have. So, I just need to two columns "CliCar_ClientsID" and "CliCar_CarsID", the will be my index keys. Even thus do I need to create a Primary Key Column "CliCar_ID"?
