Adding a number to the table using INSERT writes an error?

Question

MySQL

There is a reputation column, I want to add numbers there, but something doesn't work.
Writing:

INSERT INTO users (reputation) VALUES
(500),
(324);

And it’s understandable because I need to go to a specific place, then I thought that I could also twist WHERE, but something went wrong.

INSERT INTO users (reputation) VALUES WHERE id = 1
(500),
(324);

Answer 1

UPDATE needed here
UPDATE users SET reputation = 500 WHERE id = 1;
