求SQL语句,根据输入开始、结束日期得出结果
输入2007-7-10,2007-7-27   得到如下结果

2007-7-10   ~   2007-7-15       56628 523826.446 1043341
2007-7-16   ~   2007-7-22       81800 987373.733 2222985.5
2007-7-23   ~   2007-7-27       42019 352733.062 704981

按周一到周日的方式给出结果

------解决方案--------------------
select datepart(week,rq),sum(...) from 表 group by datepart(week,rq)
------解决方案--------------------
select (case when datepart(week,min(rq))=datepart(week, '2007-7-10 ') then '2007-7-10 ' else convert(varchar(10),DATEADD(wk,DATEDIFF(wk,0,min(rq)),0),120) end)+ ' ~ '+
(case when datepart(week,min(rq))=datepart(week, '2007-7-27 ') then '2007-7-27 ' else convert(varchar(10),DATEADD(wk,DATEDIFF(wk,0,min(rq)),6),120) end)
,sum(shl),sum(chb),sum(je)
from #表 where rq between '2007-7-10 ' and '2007-7-27 '
group by datepart(Week,dateadd(d,-1,rq))
-------------最好将日期参数格式一致
2007-7-10 ~ 2007-07-15 56628 523826.4460 1043341.0000
2007-07-16 ~ 2007-07-22 81800 987373.7330 2222985.5000
2007-07-23 ~ 2007-7-27 42019 352733.0620 704981.0000

------解决方案--------------------
或者先按给定时间段得出所有周,再join 子陌红尘的结果,效率会提升.
------解决方案--------------------
参数格式一致-----如果给的参数就是2007-07-10形式的就不用象下面要进行转换了
then '2007-7-10 ' 改为 convert(varchar(10), '2007-7-10 ',120),另个一个类似
语句---大家帮忙,我也想个简单的


------解决方案--------------------
declare @Test table(rq datetime, shl int, chb money, je money)
