The management of JustLee Books has submitted two requests. The first is for a mailing list of all customers stored in the CUSTOMERS table. The second is for a list of the percentage of profit generated by each book in the BOOKS table. The requests are as follows:
1. Create a mailing list from the CUSTOMERS table. The mailing list should display the name, address, city, state, and zip code for each customer. Each customer’s name should be listed in order of last name followed by first name, separated with a comma, and have the column header “Name.” The city and state should be listed as one column of output, with the values separated by a comma and the column header “Location.”
2. To determine the percentage of profit for a particular item, subtract the item’s cost from the retail price to calculate the dollar amount of profit, and then divide the profit by the item’s cost. The solution is then multiplied by 100 to determine the profit percentage for each book. Use a SELECT statement to display each book’s title and percentage of profit. For the column displaying the percentage markup, use “Profit %” as the column heading.
