轉換合併連接成BIML - 需要NumKeyColumns改爲1

Question

我幾乎準備了BIML文件，但我還有一個問題

我試圖把標準合併加入到BIML 和99級％的作品，和該組件生成和DTSX製作，但 我不能設置numKeyColumns值隨時隨地

<properties> 
      <property dataType="System.Int32" description="Specifies the type of join to perform." name="JoinType" typeConverter="JoinType">0</property> 
      <property dataType="System.Int32" description="Specifies the number of columns in the ordering key." name="NumKeyColumns">0</property> 
      <property dataType="System.Boolean" description="Indicates whether the null values are treated as equal values." name="TreatNullsAsEqual">true</property> 
      <property dataType="System.Int32" description="Indicates the requested maximum buffers per input before blocking." name="MaxBuffersPerInput">5</property> 
      </properties> 

我可以設置jointype 但是，當產生DTSX將在0填補我找不到NumKeyColumns 但是是必須是1

這是BIML合併連接（不傳入的連接）

  <MergeJoin Name="Merge Join" JoinType="FullOuterJoin"> 
      <LeftInputPath OutputPathName="Source.Output"> 
      <Columns> 
       <Column SourceColumn="BK" IsUsed="true" SortKeyPosition="1" TargetColumn="sBK" /> 
       <Column SourceColumn="hbSource" IsUsed="true" /> 
      </Columns> 
      </LeftInputPath> 
      <RightInputPath OutputPathName="Dwh Destination.Output"> 
      <Columns> 
       <Column SourceColumn="BK" IsUsed="true" TargetColumn="dBK" /> 
       <Column SourceColumn="hbDestination" IsUsed="true" /> 
      </Columns> 
      </RightInputPath> 
     </MergeJoin> 

任何幫助是極大的讚賞

我覺得你失蹤了MergeJoin的JoinKey屬性。添加它可以釋放一個語法正確的SSIS包。不管它在邏輯上是否正確都是另一回事;）

讓我知道如果這不是你想要做的。樂於幫助，愛Biml。
