Using MySQL Workbench, reverse engineer the tiny_video schema to create the ERD.

INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Instructions:

Use the ‘Tiny Video’ SQL script file found below

Paste the contents of this script into a query tab of MySQL Workbench and execute it. This will create the schema named tiny_video and populate it for you. After running the script, you no longer need it.

Using MySQL SELECT commands answer the questions listed below using the tiny_video schema. Read each question carefully! 

Copy/paste your SQL query, and the output for each problem, into the document and submit 

Assignment Details:

1. (1 point) Using MySQL Workbench, reverse engineer the tiny_video schema to create the ERD. Add a text box to display your name within the ERD. Include a screenshot of your results here. This ERD is useful to help you determine which tables to use for the remainder of the assignment.

 

1. (4 points) Determine your startup investment:  write a query to return title, year_released, cost, genre, copies and purchase_price. The results should be sorted by the purchase date from newest to oldest.

 

1. (4 points) Inventory considerations: write a query to display video id, title, cost and rental id. Only display videos that were never rented or never returned from their prior rental.

 

1. (5 points) Write a query to display membership name (concatenate the first name and last name with a space between them into a single column) called member_name. Add two additional columns:

 

1.

 . rental_count: to display how many times each member has rented

a. videos_rented: to display the number of videos each member has rented

 

1. (5 points) Write a query to display membership id, first name and last name for any member who has no rental history.

 

1. (6 points) Using a subquery, write a query to display membership id, first name and last name for any member who has rented multiple times. Does this match your results from Question 4?

Script is below
