MySQL:GROUP_CONCAT s ORDER BY COUNT?

Našel jsem řešení sám pomocí dílčího dotazu:

SELECT 
  SUBSTRING_INDEX(
    GROUP_CONCAT(DISTINCT name ORDER BY CountName DESC SEPARATOR '||')
  , '||', 1),
  address,
  postalcode,
  place,
  phone
FROM (

  SELECT name, address, postalcode, place, phone , COUNT(name) AS CountName
  FROM addresses
  GROUP BY name, postalcode, phone
  ORDER BY COUNT(name) DESC

) as a
GROUP BY postalcode, phone

Zajímalo by mě, zda to lze provést bez dílčího dotazu.
