SQL Reference

Quick Reference

The OR keyword is used with the WHERE keyword to include rows where at least one of multiple conditions are true.

The following selects all fields from the Customers table where the country is USA OR Canada.

SELECT * FROM Customers
WHERE country = 'USA' OR country = 'Canada';

SQL Notes:

  • Any work being done to modify the structure of a database or delete tables or the the database itself should only be done after making a recent backup

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.
