• Write a T-SQL comment above each SQL statement you write, stating your name, the task you are solving, and the purpose of the code. For example, “Harpreet. Q1. Creating a database” and “Harpreet Q1: Creating a table”, above the statements required for question 1. • Paste all the SQL code that you write into your MS Word document. That is, paste it as plain text • Paste screenshots from Microsoft SQL Server into your MS Word document. The screenshots should show your code along with the relevant messages window and/or outputs window .
 
Note: o For screenshots, keep the images small by using tools like Windows-Shift-S or the MS Word Screenshot tool. Don’t clip the entire screen or a whole window. o Note that you could gather up all of your solutions for Tasks 2A and Task 2b into 2 batches and run each batch in one hit. o Where necessary, attach labels to the screenshots in your MS Word document so as to make it clear which screenshot or portion of a screenshot belongs to which solution. Task 2a (35 Marks) 1. Write two CREATE statements. One to build a database named “PartyKids” and one to build within it a table named “Customer” which will store details about PartyKids customers.
 
The columns should match the attributes listed in your ER Diagram. All columns should be required columns (that is, don’t allow NULL values). 2. Use a single INSERT statement to create the details of 7 customers. Name one of the customers “John P Smith” and record his address as 12/1 Flinders St, Melbourne 3000. [Note: If you didn’t include address details in the Customer entity in your ER Diagram, do so now and then redo task 2a.1] 3. Use a SELECT statement to display full details of all customers 4. Change the address of John Smith to 15/1 Flinders Street and then display the name and address only of all customers 5. Display the details of all customers whose first name that starts with the letter “J” 6. Display the details of all customers who live in Victoria. Note that all Victorian postcodes are in the 3000’s and no other states use the 3000’s.

Add a 2nd table to your database. o It should store details about bookings made by a customer so name it “Booking” or something similar. If your ER diagram doesn’t show a customer entity linked to table that lists bookings (party hires) made by customers, then add one now.
 
Ensure your Booking table contains, at the minimum, attributes to store the date of the booking and any customer feedback. o Build a relationship between the Booking table and the Customer table and make it impossible to create a new Booking that doesn’t belong to an existing Customer. o Insert the details of at least 6 bookings. Enter details into every column of each record. The bookings should all belong to just 3 customers – 1 for one customer, 2 for another, and 3 for the 3rd . 9. Use a DELETE statement to try to delete a customer who has a booking. It should not be possible. 10. Display all bookings grouped by customer. Display full booking details, but don’t show any customer details. 11.
 
Display the customer names and booking dates of all customers who have made a booking and sort them from the most recent booking to the least recent. 12. Display the names of customers who have not yet made a booking. Task 2b (10 Marks) 13. Create all the tables you have drawn up in your ER Diagram and build the relationships between them. Choose your data types carefully. Note that you will need to buid the tables on the “one” side before the tables on the “many” side. 14. Add at least 3 records to every table and then display them all. Note that you will need to insert records into the tables on the “one” side before inserting into tables on the “many” side. 15. Display the names of all customers who have rented inflatables 16. Display the names of all customers who have rented chairs or inflatables 17.
