Question

我想将下面SSIS包中的转换器更改为SQL查询：

（TYPTRF ==“O”？（NUMCPT_ORD ==“4000328702”？“005000DY”:( ISNULL（NUMCLI_ORD）？“”：NUMCLI_ORD））:( NUMCPT_BEN ==“4000328702”？（ISNULL（NUMCLI_BEN_BAN）？ “”：NUMCLI_BEN_BAN）:( ISNULL（NUMCLI_BEN）？“”：NUMCLI_BEN）））

请帮帮我。我是SSIS的新手

感谢。

Answer 1

SQL案例

CASE WHEN TYPTRF = 'O'
THEN CASE WHEN NUMCPT_ORD = '4000328702'
          THEN '005000DY'
          ELSE CASE WHEN NUMCLI_ORD is null
                    THEN ''
                    ELSE NUMCLI_ORD END
            END
ELSE CASE WHEN NUMCPT_BEN = '4000328702'
          THEN CASE WHEN NUMCLI_BEN_BAN is null
                    THEN ''
                    ELSE NUMCLI_BEN_BAN END
          ELSE CASE WHEN NUMCLI_BEN is null
                    THEN ''
                    ELSE NUMCLI_BEN END
          END       
END

已修改（MS SQL）：

CASE WHEN TYPTRF = 'O'
THEN CASE WHEN NUMCPT_ORD = '4000328702'
          THEN '005000DY'
          ELSE isnull(NUMCLI_ORD, '')
          END
ELSE CASE WHEN NUMCPT_BEN = '4000328702'
          THEN isnull(NUMCLI_BEN_BAN,'')
          ELSE isnull(NUMCLI_BEN,'')
          END       
END

和Gareth说，你可以这样做：

CASE WHEN TYPTRF = 'O'
THEN CASE WHEN NUMCPT_ORD = '4000328702'
          THEN '005000DY'
          ELSE isnull(NUMCLI_ORD, '')
          END  WHEN NUMCPT_BEN = '4000328702'
               THEN isnull(NUMCLI_BEN_BAN,'')
               ELSE isnull(NUMCLI_BEN,'')
               END

Answer 2

你需要大量案例陈述！

试试这个！

select case when TYPTRF='O' then NUMCPT_ORD='4000328702' else '005000DY' end,
       case when ISNULL(NUMCLI_ORD)='' then 'NUMCLI_ORD' else end,
       case when NUMCPT_BEN ='4000328702' then '' else NUMCLI_BEN_BAN end,
       case when (ISNULL(NUMCLI_BEN)=''  then '' else NUMCLI_BEN end
