trouble with two conditions

Attempting a challenge that wants me to use the "or" condition. select * from users where last_name = "Hinkley" or "Pettit";

that is what I have used, the challenge is saying It is expecting two columns. Though it says it wants "all users". Not sure where the correction is needed.

There is a couple ways to do this. First using OR

SELECT * FROM users WHERE last_name = "Hinkley" OR last_name = "Pettit";

This can also be done by using IN and specifying a list of values

SELECT * FROM users WHERE last_name IN ("Hinkley", "Pettit");
