需求：需要做一个统计
网站是这样的：网站上有  视频频道、图片频道、新闻频道  等

需要做一个统计，能够统计这几个频道 中每个资源 某个小时、 某天、某周、某月、某年、总的 访问的次数

从上述需求看，只要统计每个资源，一天24 个小时的访问量 然后分类汇总就可以 算出  某天、某周、某月、某年、总的 范围的次数

原理就是这样。


表结构如下：
[Channel] 频道表
ID
Name    //频道名称

[Video] 视频表
ID
...

[Photo] 图库表
ID
... 

[News]  新闻表
ID
... 


存储过程用了下面的两张表详细的写下：

[PV] 表
[ID] [int] IDENTITY(1,1) NOT NULL,  [ChannelID] [int] NOT NULL,//频道ID [SourceID] [int] NOT NULL,//源ID [Times] [int] NOT NULL,//次数 [Y] [smallint] NULL,//年  如  2000  [M] [tinyint] NULL,//月   如  12 [W] [tinyint] NULL,//周  如  50  [D] [tinyint] NULL,//日   如  21 [H] [tinyint] NULL//小时 如  16


[PVS]  汇总结果表 [ID] [int] IDENTITY(1,1) NOT NULL, [ChannelID] [int] NOT NULL,//频道ID [SourceID] [int] NOT NULL,//源ID [HourRate] [float] NULL,//当前小时与上个小时相比上升的速率 [HourTimes] [int] NULL,//当前小时访问的次数 [DayRate] [float] NULL,//今天与昨天相比上升的速率 [DayTimes] [int] NULL,//今天访问的次数 [WeekRate] [float] NULL,//当周与上周相比上升的速率 [WeekTimes] [int] NULL,//当周访问的次数 [MonthRate] [float] NULL,//当月与上月相比上升的速率 [MonthTimes] [int] NULL,//当周访问的次数 [YearRate] [float] NULL,//今年与上一年相比上升的速率 [YearTimes] [int] NULL,//今年访问的次数 [Total] [int] NULL//访问的总次数
