排序sql查询

SELECT u.id AS userid,
       CASE
           WHEN h.receiver_user_id = u.id
                AND h.sender_user_id IS NOT NULL THEN 'Received'
           WHEN h.sender_user_id=u.id THEN 'Given'
           ELSE NULL
       END AS TYPE,
       h.sentiment AS sentiment,
       h.context AS context,
       '{0}' AS time_period,
       COUNT(*) AS value
FROM "User" u,
     "HoorahTransaction" h
WHERE (u.id= h.receiver_user_id
       OR u.id=h.sender_user_id)
  AND sentiment IN ('+',
                    '-')
  AND h.created>'{0}'
  AND h.created<'{1}'
GROUP BY userid,
         TYPE,
         sentiment,
         context
