Summary

Instruction

Ok, but can we actually purchase from the store?

Exercise

Select all the information from the single_rental table.

Now, let's get down to business. The first possibility in our store is to rent a single movie for a certain period of time. Each rental has an id, rental_date (when the rent starts), rental_period (in days), the platform (desktop, mobile or tablet), customer_id, movie_id, payment_date (you can pay a few day after you rent) and the payment_amount, or the price.
