SQL连接和条件和,sql,sql-server,group-by,sum,inner-join,Sql,Sql Server,Group By,Sum,Inner Join,我有两个表格，设置如下： PMmx-起点-终点矩阵的表格版本 Origin Destination Trips 1 1 0.2 2 1 0.3 3 1 0.4 . . . . . . 1 1101 0.6 2 1101 0.7 3 1101

我有两个表格，设置如下：

PMmx

-起点-终点矩阵的表格版本

Origin  Destination Trips
1           1        0.2
2           1        0.3

ZE

-具有区域等效性的表格

Precinct    Zone
1           1101
2           1102
3           1111

我想在

PMmx

表中选择与

ZE

表中的

Zone

列匹配的行条目。例如：

Origin  Destination Trips
1         1101       0.6
2         1101       0.7
3         1101       0.8
.          .          .
.          .          .     
1101       1         0.2
1101       2         0.3
1101       3         0.4

我还想创建一个名为

Distribution

的新列，该列计算

行程/（总行程）

，其中总行程将在特定区域编号上求和（通过

Origin

或

Destination

取决于哪个列与区域等效

zone

编号匹配）

例如，对于

Origin

1、

Destination

1101，我希望该行条目的新

Distribution

值为

0.6/（0.6+0.7+0.8）

我尝试了以下代码

SELECT 
      PMmx.Origin                  as Origin
     ,PMmx.Destination             as Destination
     ,PMmx.Trips/sum(PMmx.Trips) as 'Distribution'
FROM PMmx

inner join ZE on Origin=ZE.Zone or Destination=ZE.Zone 

Group by Origin, Destination, Trips

我不确定这是否会产生正确的结果，因为如果没有group by子句，我得到的列“2DVISUM\U 2031PMX\U unpiv.Origin”在选择列表中无效，因为它既不包含在聚合函数中，也不包含在group by子句中。如果有group by子句，我得到的列“2DVISUM\U 2031PMmx\U unpiv.Origin”会遇到被零除的错误。

从

内部联接中

不应该有任何

和

为零，因此我不确定为什么会出现此错误

请帮忙

编辑：我现在使用查询得到重复的行

with cte as (
  select
     origin, destination, trips
  , SUM(Trips) over(partition by Pmx.Origin) sum_trips
  , trips / SUM(Trips) over(partition by Pmx.Origin) trips_div
  from Pmx
  inner join ZE on Pmx.Origin = ZE.Zone
  )
select
origin, destination, trips, sum_trips, trips_div
from cte
union all
select
destination, origin, trips, sum_trips, trips_div

已更新表以显示错误：

1101  1211  0.50    0.50    1.00000000000000000000000000

编辑2:我想创建一个“if语句”，这样如果

Pmx.origin=ZE.Zone

那么

trips\u div

是

trips/SUM（trips）over（按Pmx.origin划分）

如上所述。但是，如果

Pmx.origin=ZE.Zone

和

Pmx.destination=ZE.Zone

那么我希望

trips\u div

仍然是

trips/SUM（trips）over（按Pmx.origin划分）

。当

Pmx.origin不等于ZE.Zone

和

Pmx.destination=ZE.Zone

时，则

trips/SUM（trips）over（按Pmx.destination划分）

。我尝试了各种各样的

case when

语句，但似乎无法使其发挥作用

我希望输出为：

origin destination trips sum_trips trips_div

    1     1101  0.20    2.10    0.0952380952380952
    2     1101  0.30    2.10    0.1428571428571429
    3     1101  0.40    2.10    0.1904761904761905
    1101    1   0.20    1.50    0.1333333333333333
    1101    2   0.30    1.50    0.2000000000000000
    1101    3   0.40    1.50    0.2666666666666666
    1101  1211  0.60    1.50    0.4000000000000000
    1211  1101  0.50    0.50    1.0000000000000000

如果我理解您的要求，我认为您可以使用稍微不同的方法来求和，从而使该求和在源表的每一行上都可用。这样，就不需要GROUPBY子句了

非常感谢你！当我被困于如何正确处理问题时，我最终将问题分解成多个表，并以重复行的方式结束（一定是因为连接不正确）。一旦读了你的帖子，我就用这种方式重新做了一遍，一切似乎都很有效！非常感谢。我说得太快了，你已经用过了！我现在似乎得到了源和目标都匹配等价表ZE的条目的重复行。例如，在Pmx中，起点为1101，终点为1102。我似乎不明白为什么会发生这种情况？我不知道您是否可以添加允许复制问题的示例数据。似乎通过上面的查询1，我得到了两行用于起点1101目的地1102，因为行程看起来不同，因为它从起点1102目的地1101条目获取行程，并将其列为起点1101目的地1102。好的，我现在会添加更多的数据。我已经用最后的编辑更新了我的问题-谢谢@Used_By_！对“编辑2”的响应请参见案例表达式为

案例，当Pmx.origin ZE.Zone和Pmx.destination=ZE.Zone然后trips/SUM（trips）over（按Pmx.destination划分）或者trips/SUM（trips）over（按Pmx.origin划分）end

，但这对结果没有影响。
