Question

如果任何值存在于重复单元号的三列中的任何一列中，我想要求和。如果我使用以下查询，则会出错。任何帮助赞赏。谢谢

select RANK() OVER(PARTITION BY unitNumber order by tableA.id) as unitnumber, ColA, ColC, ColB 
from tableA join 
     tableB on tableA.id = TableB.id
where unitNumber > 1
  and tableB .adm_Date between 01-01-2013 and 12-31-2013

Data:

 unitNumber colA  colB   ColB
  235       402   88     null
  245       null  501    522
  255       110   550    null
  245       85    null   101
  215       90    null   20
  275       852   225    null
  215       70    null   20
  225       null  null   null

输出应为

  unitNumber   colA    colB    ColB
    235         402     88     null
    245          85    501     623------added the values in colA, ColB
    275         852    225     null
    215         160   null     40 ------added the calues colA and ColB

你不需要排名功能。你需要的只是按UnitNumber分组。我基于您的源和目标数据来查询。

SELECT UnitNumber, SUM(ISNULL(ColA, 0)) ColA, SUM(ISNULL(ColB, 0)) ColB, SUM(ISNULL(ColC, 0)) ColC 
from tableA join 
     tableB on tableA.id = TableB.id
where unitNumber > 1
  and tableB.adm_Date between 01-01-2013 and 12-31-2013
GROUP BY UnitNumber

假设所有数据都在同一个表中

SELECT UnitNumber, SUM(ISNULL(ColA, 0)) ColA, SUM(ISNULL(ColB, 0)) ColB, SUM(ISNULL(ColC, 0)) ColC 
from tableA 
where unitNumber > 1
  and tableA.adm_Date between 01-01-2013 and 12-31-2013
GROUP BY UnitNumber

选择并添加重复记录的值
