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
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.”
