Expert Solution & Answer
Chapter 23.5, Problem 12SC
Explanation of Solution
Query for displaying the amount due:
In the given program, the amount due can be displayed in two ways:
- Compute using loop for displaying line items.
- Else, issue a query for displaying line items.
The below SQL query is used to compute and display the line items amount due:
/* Display the amount due of line items */
SELECT SUM (Product.Price * LineItem.Quantity)
FROM Product, LineItem
WHERE Product.Product_Code = LineItem.Product_Code
AND LineItem.Invoice_Number = ?
Explanation:
- The above “SELECT” statement calculates and displays the “SUM(Product.Price * LineItem.Quantity)” columns from the “Product and LineItem” tables where “Product.Product_Code” is equal to “LineItem.Product_code” and “LineItem.Product_Code” is equal to “?”.
- “SUM(Product.Price * LineItem.Quantity)” – It finds and displays the total line items amount due related to the invoice number.
- “SUM” – It is a function used to calculate the sum of a field.
- “Product...
- “SUM(Product.Price * LineItem.Quantity)” – It finds and displays the total line items amount due related to the invoice number.

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:
