Explore primary keys and auto increment in the secular database, using the film table and film_id to ensure unique, ordered rows and enable foreign key relationships.

Learn how to create a primary key in MySQL by redefining the customers table with an auto incrementing id column, inserting rows, and verifying the incremental keys.

Explore foreign keys as the counterpart to primary keys, and how a join table links actors to films using a composite key, with constraints ensuring data integrity.

Create a foreign key from customers.state_id to states.id by adding state_id and defining on update cascade. Observe how on update cascade and on delete cascade enforce referential integrity.
