James River Jewelry is a small jewelry shop. While James River Jewelry does sell typical jewelry purchased form jewelry vendors, including such items as rings, necklaces, earrings, and watches, it specializes in hard-to-find Asian jewelry. Although some Asian jewelry is manufactured jewelry purchased from vendors in the same manner as the standard jewelry is obtained, many of the Asian jewelry pieces are often unique single items purchased directly from the artisan who created the piece (the term manufactured would be an inappropriate description of these pieces). James River Jewelry has a small but loyal clientele, and it wants to further increase customer loyalty by creating a frequent buyer program. In this program, after every 10 purchases, a customer will receive a credit equal to 50 percent of the average of his or her 10 most recent purchases. This credit must be applied to the next (or 11th) purchase.

Assume that James River designs a database with the following tables.

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

PURCHASE (InvoiceNumber, InvoiceDate, PreTaxAmount, CustomerID)

PURCHASE_ITEM (InvoiceNumber, InvoiceLineNumber, ItemNumber,

RetailPrice)

ITEM (ItemNumber, ItemDescription, Cost, ArtistLastName,

ArtistFirstName)

The referential integrity constraints are:

CustomerID in PURCHASE must exist in CustomerID in CUSTOMER

InvoiceNumber in PURCHASE_ITEM must exist in InvoiceNumber in PURCHASE

ItemNumber in PURCHASE_ITEM must exist in ItemNumber in ITEM

Assume that CustomerID of CUSTOMER, ItemNumber of ITEM, and InvoiceNumber of PURCHASE are all surrogate keys with values as follows:

CustomerID Start at 1 Increment by 1

InvoiceNumber Start at 1001 Increment by 1

ItemNumber Start at 1 Increment by 1

Use data you have generated as part of completing the other Assignments. Name your database JRJ.

Using Access Write SQL statements and answer questions for this database as follows:

{C}A. Write SQL CREATE TABLE statements for each of these tables.

{C}B. Write foreign key constraints for the relationships in each of these tables.

{C}C. Write SQL statements to insert some sample data into these tables. Assume that surrogate key column values will be supplied by the DBMS.

{C}D. Write SQL statements to list all columns for all tables.

{C}E. Write an SQL statement to list ItemNumber and ItemDescription for all items that cost more than $100.

{C}F. Write an SQL statement to list ItemNumber and ItemDescription for all items that cost more than $100 and were produced by an artist with a last name ending with the letters son.

{C}G. Write an SQL statement to list LastName and FirstName of customers who have made at least one purchase with PreTaxAmount greater than $200. Use a subquery.

{C}H. Answer part G but use a join using JOIN ON syntax.

{C}I. Write an SQL statement to list LastName and FirstName of customers who have purchased an item that costs more than $50. Use a subquery.

{C}J. Answer part I but use a join using JOIN ON syntax.

{C}K. Write an SQL statement to list LastName and FirstName of customers who have purchased an item that was created by an artist with a last name that begins with the letter J. Use a subquery.

{C}L. Answer part K but use a join using JOINON syntax

{C}M. Write an SQL statement to show the Name and sum of PreTaxAmount for each customer. Use a join using JOIN ON syntax.

{C}N. Write an SQL statement to show the sum of PreTaxAmount for each artist (hint: the result will have only one line per each artist). Use a join using JOIN ON syntax, and sort the results by ArtistLastName then ArtistFirstName in ascending order. Note this should include the full PreTaxAmount for any purchase in which the artist had an item.

{C}O. Write an SQL statement to show the sum of PreTaxAmount for each artist but exclude any items that were part of purchases with PreTaxAmount over $25. Use a join using JOIN ON syntax, and sort the results by ArtistLastName and ArtistFirstName in descending order.

{C}P. Write an SQL statement to show which customers bought which items, and include any items that have not been sold. Include CUSTOMER.LastName, CUSTOMER.FirstName, InvoiceNumber, InvoiceDate, ItemNumber, ItemDescription, ArtistLastName, and ArtistFirstName. Use a join using JOIN ON syntax, and sort the results by ArtistLastName and ArtistFirstName in ascending order.

{C}Q. Write an SQL statement to modify all ITEM rows with an artist last name of Baxter to an artist first name of Rex.

{C}R. Write SQL statements to switch the values of ArtistLastName so that all rows currently having the value Baker will have the value Baxter and all rows currently having the value Baxter will have the value Baker.

{C}S. Given your assumptions about cascading deletions in your answer to part B, write the fewest number of DELETE statements possible to remove all the data in your database but leave the table structures intact. Do not run these statements if you are using an actual database!
