Question

假设我有两张桌子

税金
产品

我想选择产品价值的总和乘以税表中各自的增值税值，作为产品日期小于税收日期且mDate小于产品日期的百分比，按增值税分组或ttid

例如

        Taxes                                          products

 ttid     date    value  mDate                    Vat    value    date
  0     02-06-11    20    03-07-11                0       15    01-07-11
  1     03-07-11    10    03-08-11                0       15    01-07-11
  0     03-07-11    14    03-08-11                0       15    02-08-11
  1     03-08-11    15    03-09-11                1       10    04-07-11
                                                  1       10    06-08-11
                                                  1       10    08-09-11  --this will not include

所以我的结果会是这样的。

TTId   Value
0       3+3+2.1=8.1
1       1.5+1=2.5

到目前为止我写的查询。

select   sum
          ( 
            (cast(t.Value as float)
             *
            (cast(x.value as float)/100)
          )
    as 'Vat'
   ,x.ttid
 from prducts t 
,taxes x where x.ttid=t.vat  and  x.mDate>t.date and x.date<=t.date
group by x.ttid

有人会帮助我吗？

Answer 1

这里有一些问题：

正如评论中所述，您已+后跟*

在税表中date的值始终小于mdate。您的WHERE测试有x.date>t.datee and x.mDate<=t.date，表示x.date大于x.mDate。这将永远是假的

你在t.date条款中加了WHERE个额外的e

您拼错了products作为表格的名称。

此外，使用t作为products和x的别名作为tax的别名实在令人困惑。

Answer 2

SELECT
   SUM( t.Value *
     ISNULL((SELECT TOP 1 value FROM taxes x where x.ttid=t.vat and t.date BETWEEN x.date AND x.mDate order by t.datee), 100)/100) as 'Vat'
FROM prducts t

Answer 3

select sum(Vat)'Vat',itemvat,sum(productvalue)'ProductValue' from
(
SELECT
 t.vat,
t.value,
   isnull(t.value *
     (SELECT TOP 1 value FROM #TMP x where x.ttid=t.vat  and 
 convert(varchar,cast(x.effectiveDate as datetime),3)>convert(varchar,cast(t.date as datetime),3)
and convert(varchar,cast(x.mDate as datetime),3)<=convert(varchar,cast(t.date as datetime),3)

)/100,'5') 
as 'Vat'
FROM products t  
) 
as t where Vat<>'5' group by itemvat

从2个表中选择日期范围之间的数据
