我几乎准备好使用 BIML 文件，但我还有一个问题

我试图将标准的 Merge Join 放入 biml 和 99% 的工作，生成组件并制作 dtsx 但我无法在任何地方设置 numKeyColumns 值

 <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>

我可以设置 jointype 但是当生成 dtsx 时找不到 NumKeyColumns 它将填写 0 但必须为 1

这是 biml 中的合并连接（没有传入连接）

            <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>

任何帮助是极大的赞赏

我认为您缺少 MergeJoin 的 JoinKey 属性。添加允许发出语法正确的 SSIS 包。逻辑上是否正确是另一回事；）

如果这不是你想要做的，请告诉我。乐于助人，爱 Biml。
