I've seen things like

Code: Select all

INSERT INTO moviedb.genre (GenreID,GenreName)
VALUES ('18', 'Drama'),
    ('16', 'Animation')
ON DUPLICATE KEY UPDATE
  GenreName = VALUES(GenreName);

Try using the values() part where you want to set the value of the updated field.
Also as sim_name is probably your primary key - you don't need that in your update part.
