261. RIGHT JOIN

[joke mode ON]

The RIGHT JOIN is the LEFT JOIN for left-handed people. 😃 🙈

[joke mode OFF]

RIGHT JOIN returns all records from the right table and all the matched records from the left table.

Here’s an example of RIGHT JOIN for users and purchases:

SELECT * FROM purchases p RIGHT JOIN users u ON p.user_id = u.id 

To be honest, I haven’t used RIGHT JOIN a single time during the last 5 years. The only exception is the interview question “Give me all JOIN types you know.” 😁
