Sample Solution:

-- Selecting specific columns from the Product table where Color is 'Red'
SELECT Name, Color, ListPrice  

-- From the Production schema's Product table
FROM Production.Product  

-- Filtering the results to include only rows where Color is 'Red'
WHERE Color = 'Red'  

-- UNION ALL combines the results of two SELECT statements, including duplicates
UNION ALL  

-- Selecting specific columns from the Product table where Color is 'Blue'
SELECT Name, Color, ListPrice  

-- From the Production schema's Product table
FROM Production.Product  

-- Filtering the results to include only rows where Color is 'Blue'
WHERE Color = 'Blue'  

-- Ordering the combined results by ListPrice in ascending order
ORDER BY ListPrice ASC;

Explanation:

• The SQL query retrieves data from the Product table within the Production schema.
• It selects three columns: Name, Color, and ListPrice.
• Two SELECT statements are used, each filtering the results based on a specific color (Red and Blue).
• The UNION ALL operator combines the results of both SELECT statements, including duplicates.
• As a result, the combined result set will contain products that are either red or blue.
• The ORDER BY clause specifies the sorting criteria for the combined result set, ordering by ListPrice in ascending order.
• This will arrange the products from lowest to highest list price, regardless of their color.
