我有以下MySQL数据库:

http://sqlfiddle.com/#!2/7d82f

我如何确保获得按时间分组的最大金额? 所以我会得到:

Max(hitId)  |     dte        |  time
    1       |    2015-01-18  | 19:00:00 
    2       |    2015-01-18  | 20:00:00 
    1       |    2015-01-18  | 21:00:00 
    2       |    2015-01-18  | 22:00:00 

但我不想得到上次约会。 所以只有日期是'2015-01-18'(或者我放的任何东西)

SELECT COUNT( hitId ) AS Max_hits, dte AS sDate, TIME AS sTime
FROM hitcounter
WHERE dte =  '2015-01-18'
GROUP BY sTime
ORDER BY sDate ASC
