21. Add rental for movie "Academy Dinosaur" by Charlotte Hunter from Mike Hillyer at Store 1. You can use current date for the rental_date column in the rental table. Hint: Check the columns in the table rental and see what information you would need to add there. You can query those pieces of information. For eg., you would notice that you need customer_id information as well. To get that you can use the following query:

    select customer_id from sakila.customer
    where first_name = 'CHARLOTTE' and last_name = 'HUNTER';

    Use similar method to get inventory_id, film_id, and staff_id.

    • Check if there are any non-active users
    • Create a table backup table as suggested
    • Insert the non active users in the table backup table
