Sample Solution:

-- Selecting the 'productnumber' and 'name' columns 
SELECT productnumber, name

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

-- Filtering the results to include only rows where the rightmost character of the 'name' column is 'S', 'M', or 'L'
WHERE RIGHT(name,1) in ('S','M','L');

Explanation:

• The SQL query retrieves data from the product table within the production schema.
• It selects the 'productnumber' and 'name' columns.
• The RIGHT() function extracts the rightmost character of the 'name' column.
• The WHERE clause filters the results to include only rows where the rightmost character of the 'name' column is either 'S', 'M', or 'L'.
