	create table T(日期时间 datetime, 数量 int)
	insert T select '2007-1-1 19:31:25 ', 56
	union all select '2007-1-1 21:31:25 ', 35
	union all select '2007-1-1 15:31:25 ', 43
	union all select '2007-1-2 19:31:25 ', 34
	union all select '2007-1-3 15:31:25 ', 35
	union all select '2007-1-3 21:31:25 ', 65
	--按日统计
	select 日期时间=convert(char(10), 日期时间, 120), 数量=sum(数量)
	from T
	group by convert(char(10), 日期时间, 120)
	--按周统计
	select 日期时间=datepart(week, 日期时间), 数量=sum(数量)
	from T
	where year(日期时间)=year(getdate())
	group by datepart(week, 日期时间)
	--按月统计
	select 日期时间=convert(char(7), 日期时间, 120), 数量=sum(数量)
	from T
	group by convert(char(7), 日期时间, 120)
	　　实例：
	　　按日统计
	　　select sum(cniTicketCount) as STickCount,Convert(varchar(10),cnAppDate,23) as ScnAppDate from
	(select B.*,U.UserName from SystemUsers U inner join BookingDetails B on U.AutoID=B.cnvcApplyMan
	where B.cniTicketCount>0 and B.cnAppDate between '2010/09/01' and '2010/10/01') as A
	group by Convert(varchar(10),cnAppDate,23)

	　　按周统计
	　　select sum(cniTicketCount) as STickCount,datepart(week,cnAppDate)as ScnAppDate from
	(select B.*,U.UserName from SystemUsers U inner join BookingDetails B on U.AutoID=B.cnvcApplyMan
	Where B.cniTicketCount>0) as A
	group by datepart(week,cnAppDate)

	　　按月统计
	　　select sum(cniTicketCount) as STickCount,substring(Convert(varchar(10),cnAppDate,23),1,7) as ScnAppDate from
	(select B.*,U.UserName from SystemUsers U inner join BookingDetails B on U.AutoID=B.cnvcApplyMan
	Where B.cniTicketCount>0) as A
	group by substring(Convert(varchar(10),cnAppDate,23),1,7)
