Write a SELECT statement that returns one row for each customer that has orders with these columns: The EmailAddress column from the Customers table The sum of the item price in the OrderItems table multiplied by the quantiy in the OrderItems table The sum of the discount amount column in the OrderItems table multiplied by the quantiy in the OrderItems table Sort the result set in descending sequence by the item price total for each customer. 4. Write a SELECT statement that returns one row for each customer that has orders with these columns: The EmailAddress column from the Customers table A count of the number of orders The total amount for those orders (Hint: First, subtract the discount amount from the price. Then, multiply by the quantity.) Return only those rows where the customer has more than 1 order. Sort the result set in descending sequence by the sum of the line item amounts. 5. Modify the solution to exercise 4 so it only counts and totals line items that have an ItemPrice value that's greater than 400.
