Sample Solution:
-- This SQL query selects specific columns from the Production.Product table, applying filtering conditions based on Weight and Color columns.
-- Selecting columns: Name, Weight, and Color.
SELECT Name, Weight, Color
-- From the Production.Product table.
FROM Production.Product
-- Filtering the results where the Weight is less than 10.00 OR the Color is NULL.
WHERE Weight < 10.00 OR Color IS NULL
-- Ordering the results by the Name column in ascending order.
ORDER BY Name;
Explanation:
- The query retrieves data from the Product table in the Production schema.
- It selects three columns: Name, Weight, and Color.
- The WHERE clause filters the results:
- Rows are included if their Weight is less than 10.00 OR if the Color column contains NULL values.
- The OR operator allows rows to be included in the result set if either condition is met.
- Finally, the results are sorted alphabetically by the Name column in ascending order.
