新建一个统计表。每隔10分钟查询一遍数据，把统计结果插入到统计表。然后你查询统计结果时就查询这个统计表就好了。

大神有简单的demo嘛
@邪祺Gods: 没有。你查“开源调度器”，用调度器来控制执行统计的时间（有的数据库本身也支持定时操作）。另外，我不是大神，我是狗
@会长: 谢谢您。只是突然想到这个问题 我去查查。

Oracle数据库有一个比较常用的SQL，用来计算每个小时的归档日志量，与楼主所表的的类似：
SELECT trunc(first_time) "Date",
to_char(first_time, 'Dy') "Day",
count(1) "Total",
SUM(decode(to_char(first_time, 'hh24'),'00',1,0)) "h0",
SUM(decode(to_char(first_time, 'hh24'),'01',1,0)) "h1",
SUM(decode(to_char(first_time, 'hh24'),'02',1,0)) "h2",
SUM(decode(to_char(first_time, 'hh24'),'03',1,0)) "h3",
SUM(decode(to_char(first_time, 'hh24'),'04',1,0)) "h4",
SUM(decode(to_char(first_time, 'hh24'),'05',1,0)) "h5",
SUM(decode(to_char(first_time, 'hh24'),'06',1,0)) "h6",
SUM(decode(to_char(first_time, 'hh24'),'07',1,0)) "h7",
SUM(decode(to_char(first_time, 'hh24'),'08',1,0)) "h8",
SUM(decode(to_char(first_time, 'hh24'),'09',1,0)) "h9",
SUM(decode(to_char(first_time, 'hh24'),'10',1,0)) "h10",
SUM(decode(to_char(first_time, 'hh24'),'11',1,0)) "h11",
SUM(decode(to_char(first_time, 'hh24'),'12',1,0)) "h12",
SUM(decode(to_char(first_time, 'hh24'),'13',1,0)) "h13",
SUM(decode(to_char(first_time, 'hh24'),'14',1,0)) "h14",
SUM(decode(to_char(first_time, 'hh24'),'15',1,0)) "h15",
SUM(decode(to_char(first_time, 'hh24'),'16',1,0)) "h16",
SUM(decode(to_char(first_time, 'hh24'),'17',1,0)) "h17",
SUM(decode(to_char(first_time, 'hh24'),'18',1,0)) "h18",
SUM(decode(to_char(first_time, 'hh24'),'19',1,0)) "h19",
SUM(decode(to_char(first_time, 'hh24'),'20',1,0)) "h20",
SUM(decode(to_char(first_time, 'hh24'),'21',1,0)) "h21",
SUM(decode(to_char(first_time, 'hh24'),'22',1,0)) "h22",
SUM(decode(to_char(first_time, 'hh24'),'23',1,0)) "h23"
FROM V$log_history
where trunc(first_time)>sysdate-30
group by trunc(first_time), to_char(first_time, 'Dy')
Order by 1;
