Sample Solution:

-- Selecting ProductID and Name columns from the Product table where ProductID is not 3 or 4, and combining the result with the ProductModelID and Name columns from the ProductModel table using the UNION operator
SELECT 
    -- Selecting the ProductID column and Name column from the Product table
    ProductID, 
    Name  
-- Selecting data from the Product table, filtering out ProductID values 3 and 4
FROM 
    Production.Product  
-- Filtering records where ProductID is not 3 or 4
WHERE 
    ProductID NOT IN (3, 4)  
-- Combining the results with the following SELECT statement using the UNION operator
UNION  
-- Selecting the ProductModelID column and Name column from the ProductModel table
SELECT 
    ProductModelID, 
    Name  
-- Selecting data from the ProductModel table
FROM 
    Production.ProductModel   
-- Ordering the result set by Name
ORDER BY 
    Name;

Explanation:

• This SQL code retrieves ProductID and Name columns from the Product table where ProductID is not 3 or 4, and combines the result with the ProductModelID and Name columns from the ProductModel table using the UNION operator.
• The first SELECT statement selects ProductID and Name columns from the Product table, filtering out ProductID values 3 and 4.
• The WHERE clause filters records where ProductID is not 3 or 4.
• The UNION operator combines the results of the first SELECT statement with the results of the second SELECT statement, ensuring that duplicate rows are removed.
• The second SELECT statement selects ProductModelID and Name columns from the ProductModel table.
• The ORDER BY clause orders the combined result set by Name.
