It is the only means of changing, but neither inserting nor deleting, a record. The other fields are left the same. MySQL also tracks whether it is an actual change; this is reflected in the client message Rows matched: ? Changed: ? Warnings: ? . The number after "Changed:" is the number of records where the new value really differs from the old.
