Single-Table Queries
Use SQL to do the following:
1. Find the part number and description of all parts.
2. List the complete SLSREP table.

Do this in two ways.
8. Give the part number, description, and on-hand value (units on hand * price) for each part in
item class AP. (On-hand value is really units on hand * cost but we do not have a cost
column in the PART table.)
9. Give the part number, description, and on-hand value for each part whose on-hand value is at
least 1,000.
10. List the part number and description of all parts whose item class is HW or SG. Use the word

16. List the number, description, and units on hand of all parts whose number of units on hand is
more than average.
17. List the totals of the balances for the customers of each sales rep. In a second query, list only
the totals of the balances for sales reps with at least four customers.

3. For each order, list the order number and the order date as well as the part number, number of
units ordered, and quoted price for each of the order lines that make up the order.
4. Find the numbers and names of all customers who placed orders on September 5, 1991. Do
this in two ways. First, use the word IN; second, use the word EXISTS.

description, and item class of all parts that make up the order.
7. Find the numbers and names of all sales reps who represent at least one customer with a credit
