1. Use an ALTER TABLE statement to update the customers table so that the Primary Key field is an auto-increment field, then create TWO insert statements to test proper operation, using your own first and last name for one (and a name of your choice for the second one), and any data you care to imagine for the remaining fields.
2. The Vice President of Marketing for your firm wants the firms sales representatives to be able to directly view and edit customer details, but only for the state to which a particular sales representative is assigned. You have suggested that this need can be addressed with a view. For example, a view could be created for one particular state, and user account permissions for accessing that view granted only to sales representatives from that state. The VP has asked you to quickly create a simple proof-of-concept demonstrating how this might work. Complete the following steps:
3. Construct a view on the customers table called CA_CUSTOMERS that consists of all data about customers that live in Californi

b. Display the data using this view to verify that only customers that reside in California are visible.

c. Prove that It is possible to add or update records through this view by updating the record for Karina Lacy to change the spelling of Karinas last name to Lacie.

d. Display the data using the customer table to verify that the change has been made.

Show all commands in your answer sheet along with the output of the commands.

3. The Senior Customer Service Manager has requested the ability to create a report at any time that will show shipped orders that took some specified number of days to fulfill.

a. Create a view named SHIPPING_TIME that lists only customer_first_name, customer_last_name, order_date, shipped_date, and the calculated field days_to_fulfill (use the DATEDIFF function) showing the number of days between when the customer placed the order and when it was shipped. Show the data from this view.

Now lets do some queries by adding sorting and filters USING THIS VIEW, WITHOUT CHANGING IT.

b. Use the view to display the data sorted by highest to lowest days to ship

c. Use the view to display only the orders that took less than 10 days to ship.

d. Use the view to display only the orders that took more than 30 days to ship.

4. Queries that require joins and aggregate functions can be easier to construct when using a view as a temporary table. Consider a report to show total sales by artist.

a. First create a view called SalesData that displays the order_id, item_id, the calculated field ItemTotal (which is quantity times price), the title and artist_id.

b. Display the data in the SalesData view sorted by artist_id. Does this help you to visualize how to group the data to create the totals?

c. Create a query USING THIS VIEW and the appropriate aggregate function to display artist_id and the total sales for each artist.

d. Now join to the artist table in order to display the artist_name along with the total sales.

5. Now use this same method to display the total sales per customer.

a. Create a view called SalesData with the appropriate data. At a minimum you will need customer_id and the calculated item total. DO NOT use the customer table in this view, it will be joined later.

b. Display the data in your view sorted by customer_id. Does this help you to visualize how to group the data to create the totals?

c. Create a query USING THIS VIEW and the appropriate aggregate function to display customer_id and the total sales for each customer.

d. Now join to the customer table in order to display the customer_name as a single field named Customer along with the total sales. Sort the report by Total sales in descending order.
