¿Cómo escribir esta declaración SQL?

SELECT user.name, user.subject
FROM user
INNER JOIN (
    SELECT name, COUNT(1) AS occurrences
    FROM user
    GROUP BY name
  ) AS user_occurrences
  ON user.name = user_occurrences.name
ORDER BY user_occurrences.occurrences DESC, user.name ASC, user.subject ASC
LIMIT 4

editar Esto podría funcionar mejor, según el RDBMS que esté utilizando y el tamaño del conjunto de datos. Prueba ambos y compara.

SELECT user.name, user.subject
FROM user
INNER JOIN user AS user_occurrences
  ON user.name = user_occurrences.name
GROUP BY user.name --, user.subject Second GROUP BY not needed on MySQL, but it should logically be there
ORDER BY COUNT(user_occurrences.subject) DESC, user.name ASC, user.subject ASC
LIMIT 4
