Sample Solution:
-- Selecting specific columns from the Product table and adding a calculated column for price range
SELECT
-- Selecting the ProductNumber column
ProductNumber,
-- Selecting the Name column
Name,
-- Selecting the listprice column
listprice,
-- Applying a CASE statement to categorize products into price ranges
CASE
-- Condition: ListPrice is 0
WHEN ListPrice = 0 THEN 'Mfg item - not for resale'
-- Condition: ListPrice is less than 50
WHEN ListPrice < 50 THEN 'Under $50'
-- Condition: ListPrice is between 50 and 249.99
WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
-- Condition: ListPrice is between 250 and 999.99
WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
-- Default condition: ListPrice is 1000 or more
ELSE 'Over $1000'
END "Price Range"
-- Selecting data from the Product table
FROM Production.Product
-- Ordering the result set by ProductNumber
ORDER BY ProductNumber ;
Explanation:
- This SQL code selects specific columns from the Product table and adds a calculated column for price range.
- The CASE statement categorizes products into different price ranges based on their ListPrice.
- If ListPrice is 0, the product is labeled as 'Mfg item - not for resale'.
- If ListPrice is less than 50, the product is labeled as 'Under $50'.
- If ListPrice is between 50 and 249.99, the product is labeled as 'Under $250'.
- If ListPrice is between 250 and 999.99, the product is labeled as 'Under $1000'.
- If ListPrice is 1000 or more, the product is labeled as 'Over $1000'.
- The result set is ordered by ProductNumber.
