Sample Solution:
-- Selecting columns ProductName, NonDiscountSales, and Discounts
SELECT p.Name AS ProductName,
-- Calculating non-discounted sales by multiplying OrderQty and UnitPrice
(OrderQty * UnitPrice) as NonDiscountSales,
-- Calculating discounts by multiplying the non-discounted sales by UnitPriceDiscount
((OrderQty * UnitPrice) * UnitPriceDiscount) as Discounts
-- From the Production.Product table aliased as 'p'
FROM Production.Product AS p
-- Joining with the SalesOrderDetail table aliased as 'sod' based on ProductID
INNER JOIN Sales.SalesOrderDetail AS sod
ON p.ProductID = sod.ProductID
-- Ordering the result set by ProductName in descending order
ORDER BY ProductName DESC;
Explanation:
- This SQL query retrieves data from the Product and SalesOrderDetail tables.
- Comments are added to explain each part of the query for better understanding and maintenance.
- Here's a breakdown of what the query does:
- The SELECT clause specifies the columns to be retrieved: ProductName, NonDiscountSales, and Discounts.
- NonDiscountSales is calculated by multiplying OrderQty and UnitPrice.
- Discounts are calculated by multiplying the non-discounted sales by UnitPriceDiscount.
- The FROM clause specifies the source table as Production.Product aliased as 'p', indicating that it will be joined with SalesOrderDetail.
- The INNER JOIN clause joins the Product table with the SalesOrderDetail table based on the ProductID column.
- The ORDER BY clause arranges the result set by ProductName in descending order.
