I do not understand why this query does not work!!! SQL
I do not know whether I'm wrong or there is an error in the quiz
This is the question: Now we're using a database from a smartphone. It has a phone_book table. It has the columns id, first_name, last_name and phone. Update all contacts to have the first name of "Mystery" and last name of "Person".
This is my query: UPDATE phone_book SET first_name = "Mystery" AND last_name = "Person";
I showed this error:
Bummer! Was expecting 6 entries in the phone_book with the updated name. There's only 0.
I tried to use the WHERE clause but again it did not work again.

Instead of the word "
AND", just put a comma (,) between the column settings.
UPDATE phone_book SET first_name = "Mystery", last_name = "Person";
