Summary

Instruction

Single rentals are not the only option in the store!

Exercise

Select all the information from the subscription table.

Real movie lovers get a subscription instead of single rentals. Each subscription has an id, a length (in days), a start_date, a platform (same as the platforms for single rentals), payment_date, payment_amount and customer_id.
