Premiere Products database

Use SQL to make the following changes to the Premiere Products database (see Figure 1-2 in Chapter 1). After each change, execute an appropriate query to show that the change was made correctly. If directed to do so by your instructor, use the information provided with the Chapter 3 Exercises to print your output. For any exercises that use commands not supported by your version of SQL, write the command to accomplish the task.

Create a view named ORDER_TOTAL. It consists of the order number and order total for each order currently on file. (The order total is the sum of the number of units ordered multiplied by the quoted price on each order line for each order.) Sort the rows by order number. Use TOTAL_AMOUNT as the name for the order total.

a. Write and execute the CREATE VIEW command to create the ORDER_TOTAL view.

b. Write and execute the command to retrieve the order number and order total for only those orders totaling more than $1,000.

c. Write and execute the query that the DBMS actually executes.

d. Does updating the database through this view create any problems? If so, what are they? If not, why not?
