Updating a SQLite row with a value from another row

I had a table with a bunch of users and one of the users is a demo user and I wanted to copy the login token from my row to the demo user. This is how I managed to do that.

UPDATE users SET token = (SELECT token FROM users u WHERE u.id = 1) WHERE id = 2;

This will update the token column for the user with the id 2 with the value from the user with the id 1.
