Marcia Wilson owns and operates Marcia's Dry Cleaning, which is an upscale dry cleaner in a well-to-do suburban neighborhood. Marcia makes her business stand out from the competition by providing superior customer service. She wants to keep track of each of her customers and their orders. Ultimately, she wants to notify them that their clothes are ready via e-mail. To provide this service, she has developed an initial database with several tables. Three of those tables are the following:

CUSTOMER (CustomerID, FirstName, LastName, Phone, Email)

INVOICE (InvoiceNumber, CustomerNumber, DateIn, DateOut, TotalAmount)

INVOICE_ITEM (InvoiceNumber, ItemNumber, Item, Quantity, UnitPrice)

In the database schema above, the primary keys are underlined and the foreign keys are shown in italics. The database that Marcia has created is named MDC, and the three tables in the MDC database schema are shown in Figure 2-33.

The column characteristics for the tables are shown in Figures 2-34, 2-35, and 2-36. The relationship between CUSTOMER and INVOICE should enforce referential integrity, but not cascade updates or deletions, while the relationship between INVOICE and INVOICE_ITEM should enforce referential integrity and cascade both updates and deletions. The data for these tables are shown in Figures 2-37, 2-38, and 2-39. We recommend that you create a Microsoft Access 2010 database named MDC-CH02.accdb using the database schema, column characteristics, and data shown above, and then use this database to test your solutions to the questions in this section. Alternatively, SQL scripts for creating the MDC-CH02 database in SQL Server, Oracle Database, and MySQL are available on our Web site at www.pearsonhighered. com/kroenke.

Write SQL statements and show the results based on the MDC data for each of The following:

A. Show all data in each of the tables.

B. List the Phone and LastName of all customers.

C. List the Phone and LastName for all customers with a FirstName of 'Nikki'.
