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.

:point_right: Instead of the word "AND", just put a comma (,) between the column settings.

UPDATE phone_book SET first_name = "Mystery", last_name = "Person";

Thank you very much, really weird that I have not tried with comma. Usually try everything possible before i seek for help, it seems that today was not my day. Thanks again for your help Steven.
