Lab | SQL Queries 5

In this lab, you will be using the Sakila database of movie rentals. You have been using this database for a couple labs already, but if you need to get the data again, refer to the official installation link.

The database is structured as follows:

Instructions

1. Drop column picture from staff.

2. A new person is hired to help Jon. Her name is TAMMY SANDERS, and she is a customer. Update the database accordingly.

3. 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.

4. Delete non-active users, but first, create a backup table deleted_users to store customer_id, email, and the date for the users that would be deleted. Follow these steps:

   • 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
   • Delete the non active users from the table customer
