Question
Chapter 3, Problem 3.27RQ
Program Plan Intro
Display values from table:
The contents from the table can be viewed by using “SELECT” statement which comes under Data Manipulation Language (DML).
The Syntax to view the contents using asterisk (*) is as follows:
SELECT * FROM table_Name;
Selective columns can also be retrieved by replacing all the column(s) names in place of the asterisk symbol.
ORDER BY Clause:
SQL contains “GROUP BY” clause in order to sort rows. The values get sorted in ascending as well as descending order.
The keyword used to sort values in ascending order is “ASC” and for descending order is “DESC”. By default, it sorts values by ascending order.
Syntax:
SELECT column_Name1, column_Name2 FROM table_Name ORDER BY column_Name2 ASC, column_Name1 DESC;

Write the following SQL Statements:
Write a SELECT statement that returns one row for each customer that has orders with these columns:
The email_address from the Customers table
A count of the number of orders
The total amount for each order (Hint: First, subtract the discount amount from the price. Then, multiply by the quantity.)
Return only those rows where the customer has more than 1 order.
Sort the result set in descending sequence by the sum of the line item amounts.
Write a SELECT statement that answers this question: What is the total amount ordered for each product? Return these columns:
The product name from the Products table
The total amount for each product in the Order_Items (Hint: You can calculate the total amount by subtracting the discount amount from the item price and then multiplying it by the quantity)
Use the ROLLUP operator to include a row that gives the grand total.
Write a SELECT statement that answers this question: Which customers have ordered more…
PATHS is a table that contains information about paths on a number line. The
structure of PATHS is as follows, where x1 and x2 represent that there is a path
from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to
Coordinate x1 ).
NAME
ΤΥΡE
NULLABLE
X1
INT
FALSE
X2
INT
FALSE
Problem
Please write an SQL statement that returns the beginning and end point of each
path in PATHS . Sort them by the value of the beginning point in ascending order.
Constraints
• In the case where a direct path from Coordinate a to Coordinate b is
available, no path from Coordinate b to Coordinate a will be given.
|x1-x2| = 1
• No path will overlap with one another.
Example
Suppose that PATHS is as follows:
x1
x2
1
2
2

7

This table can be visualized as follows:
START
END
END

Therefore, your SQL statement must return the following:

You have the following tables:
MANAGERS (MANAGER_ID, LAST_NAME, FIRST_NAME, DEPARTMENT)
ACCOUNTS (ACCOUNT_NUMBER, MANAGER_ID, CUST_ID, BALANCE)
CUSTOMERS (CUST_ID, LAST_NAME, FIRST_NAME)
Write a SQL statement that lists account number, balance, MANAGER’s last name, CUSTOMER ID, and CUSTOMER’s last name for every account in the ACCOUNTS table.
