Question

FROM   
    DW_Stage.PreStage.FilteredCoupon  c
INNER JOIN 
    DW.Linkage l WITH (nolock)
          REPLACE([l.CouponNumber], '/', '') ON (c.CouponSeqNbr = l.CouponNumber 
                                             AND c.PNRCreateDate = l.PNRCreateDate 
                                             AND c.PNRLocator = l.PNRLocator 
                                             AND c.PrimaryDocNbr = l.PrimaryDocNbr)

因此有两条记录在CouponNumber中有一个'/'，导致我的SSIS包失败。如果我使用这个REPLACE函数，这将是最好的用途吗？或者应该在ON部分使用REPLACE功能？感谢

Answer 1

您需要replace()部分中的on。你的语法没有意义。但你也想删除方括号：

FROM DW_Stage.PreStage.FilteredCoupon c INNER JOIN
     DW.Linkage l
     ON c.CouponSeqNbr = REPLACE(l.CouponNumber, '/', '') AND
        c.PNRCreateDate = l.PNRCreateDate AND
        c.PNRLocator = l.PNRLocator AND
        c.PrimaryDocNbr = l.PrimaryDocNbr

括号ON条件也没有增加任何价值。

FROM   
          DW_Stage.PreStage.FilteredCoupon  c
          INNER JOIN 
          DW.Linkage l WITH (nolock)


              ON 
          (     
         c.CouponSeqNbr = REPLACE([l.CouponNumber], '/', '')
        AND c.PNRCreateDate = l.PNRCreateDate 
        AND c.PNRLocator = l.PNRLocator 
        AND c.PrimaryDocNbr = l.PrimaryDocNbr )

用INNER JOIN SQL Server替换
