Quick Reference
The CASE keyword is used is to create different output based on various conditions.
The following will order the customers from the Customers table by city. However, if city is NULL, then it will order by country.
SELECT name, city, country
FROM Customers
ORDER BY
(CASE
WHEN city IS NULL THEN country
ELSE city
END);
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
