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.
