Write a SELECT statement that returns one row for each customer that has orders with these columns:

d1i1m1o1n [39]

Answer:

SELECT email_address,

SUM(item_price * Quantity) AS item_price_total,

SUM(discount_amount * Quantity) AS discount_amount_total

FROM Customers c

JOIN Orders o ON c.CustomerID = o.CustomerID

JOIN Order_Items oi ON o.OrderID = oi.OrderID

GROUP BY email_address

ORDER BY item_price_total DESC

Explanation:

In this SQL statement the SELECT statement selects the following columns:

email_address

item_price

Quantity

discount_amount

There are two tables Customers and Order_Items

SUM aggregate function is used to add the values of the product of the columns discount_amount and Quantity. It is also used to get the sum of the product of two columns discount_amount and Quantity.

A new temporary column named item_price_total is used to name the sum of the product of two columns discount_amount and Quantity using AS which is ALIAS and it is used to give a name to some columns or a table.

Similarly discount_amount_total name is given to the column which calculate the sum of the product of two columns i.e. discount_amount and Quantity.

JOIN is used here to join the columns from the tables Order_items and Customers.

GROUP BY is used to group the result of rows and is used with functions like SUM. Here the rows are grouped by the email address.

ORDER BY is used to order the result. Here the result is ordered by item_price_total in descending order.

This SELECT statement can also be written as following:

SELECT c.email_address,

SUM(o.item_price * o.Quantity),

SUM(o.discount_amount * o.quantity)

FROM customer c

JOIN Order_Items o ON o.id = c.id

GROUP BY c.email_address

including how it can be stored and what types of operations we can perform. For example, we can write a program that squares num

ASHA 777 [7]

Answer:

The solution code is written in Python:

def square(num):
if type(num).__name__ == 'int':
sq_num = num * num
return sq_num
else:
return "Invalid input"
print(square(5))
print(square("Test"))

Explanation:

To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as square which take one input number, num (Line 1).

Before the num can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer, int. If so, the num will only be squared otherwise it return an error message (Line 6).

We can test our function by passing value of 5 and "Test" string. We will get program output:

25

Invalid input
