Question

我为报告编写了以下sql查询。

Select AT.OTHER_GL_CODE As ACC,
       GL.GL_ID,
       GL.GL_NAME,
       (Case When (
                      AT.OTHER_TRN_DEC = 'Cash'
                      And AT.OTHER_CR_DR = 'CR'
                  ) Then AT.OTHER_AMOUNT
             Else '0'
        End
       ) As 'CASHCR',
       (Case When (
                      AT.OTHER_TRN_DEC = 'Cash'
                      And AT.OTHER_CR_DR = 'DR'
                  ) Then AT.OTHER_AMOUNT
             Else '0'
        End
       ) As 'CASHDR',
       (Case When (
                      AT.OTHER_TRN_DEC <> 'Cash'
                      And AT.OTHER_CR_DR = 'CR'
                  ) Then AT.OTHER_AMOUNT
             Else '0'
        End
       ) As 'OTHERCR',
       (Case When (
                      AT.OTHER_TRN_DEC <> 'Cash'
                      And AT.OTHER_CR_DR = 'DR'
                  ) Then AT.OTHER_AMOUNT
             Else '0'
        End
       ) As 'OTHERDR',
       AT.OTHER_BRN_CODE BRNCODE,
       (
           Select Sum(   Case When TR.CR_DR = 'DR'
                                   And TR.BRANCH_CODE = 1000
                                   And TR.TRAN_DATE < '2017-07-01' Then TR.GL_TRN_AMT
                              Else 0
                         End
                     )
           From   COREBANKER1.dbo.GL_DAILY_TRN As TR
           Where  TR.GL_CODE = AT.OTHER_GL_CODE
       ) As DRBRFORE,
       (
           Select Sum(   Case When TR.CR_DR = 'CR'
                                   And TR.BRANCH_CODE = 1000
                                   And TR.TRAN_DATE < '2017-07-01' Then TR.GL_TRN_AMT
                              Else 0
                         End
                     )
           From   COREBANKER1.dbo.GL_DAILY_TRN As TR
           Where  TR.GL_CODE = AT.OTHER_GL_CODE
       ) As CRBRFORE
From   COREBANKER1.dbo.MAIN_OTHER_TRN As AT,
       COREBANKER1.dbo.GL_MAIN As GL
Where  AT.OTHER_BRN_CODE = 1000
       And GL.GL_ID = AT.OTHER_GL_CODE
       And AT.OTHER_BANK_DATE
       Between '2017-07-01' And '2017-07-30';

这是输出

但是我想要的输出就在这里

那么我如何更改我的查询以获得所需的结果（分组到ACC和GL_ID）？

Answer 1

快速而肮脏的方法是将整个查询和分组包装起来，这样可以防止3,4,5,6列中的重复值。

更干净的方法是获取这4列并将每个列包装在Select SUM(...)中，就像您为后面的列所做的那样。

简而言之，没有GROUP BY会给你留下重复的内容 - 我冒昧地为你提供快速而肮脏的方法的语法，见下文。

Answer 2

您可以使用CTE包围查询，然后汇总所需的字段。

WITH this as 
(
Select AT.OTHER_GL_CODE As ACC,
   GL.GL_ID,
   GL.GL_NAME,
   (Case When (
                  AT.OTHER_TRN_DEC = 'Cash'
                  And AT.OTHER_CR_DR = 'CR'
              ) Then AT.OTHER_AMOUNT
         Else '0'
    End
   ) As 'CASHCR',
   (Case When (
                  AT.OTHER_TRN_DEC = 'Cash'
                  And AT.OTHER_CR_DR = 'DR'
              ) Then AT.OTHER_AMOUNT
         Else '0'
    End
   ) As 'CASHDR',
   (Case When (
                  AT.OTHER_TRN_DEC <> 'Cash'
                  And AT.OTHER_CR_DR = 'CR'
              ) Then AT.OTHER_AMOUNT

    End
   ) As 'OTHERDR',
   AT.OTHER_BRN_CODE BRNCODE,
   (
       Select Sum(   Case When TR.CR_DR = 'DR'
