sql-server - 使用 BIML 脚本创建查找 SSIS

Question

我正在 BIMLscript 中创建一个查找来创建一个带有查找的 ssis 包。我本质上只是想演示查找的功能，所以我正在查找表格本身。当我创建包时，它似乎构建得很好。但是，当我在 VS2013 中打开它时，会出现大量错误，如下所示：

错误 1 ​​验证错误。char1: char1: LKP_char1.Inputs[Extract_Output_LKP_char1].Columns[chr_1] 具有无效错误或截断行处置。字符.dtsx 0 0

char1 是表的名称，LKP_char1 是查找的名称，chr_1 是第一列的名称。有没有人对如何尝试和调试有任何想法。

我将 LookUp 标记的 NoMatchBehavior 属性设置为“IgnoreFailure”

<Dataflow Name="<#=table.SsisSafeName#>">
    <Transformations>
     <OleDbSource Name="Extract" ConnectionName="Source">
        <DirectInput>SELECT * FROM <#=table.SchemaQualifiedName#>
        </DirectInput>
    </OleDbSource>
    <Lookup Name="LKP_<#=table.Name#>" 
        NoMatchBehavior="IgnoreFailure" 
        OleDbConnectionName="Source">
            <ExternalTableInput Table="<#=table.SchemaQualifiedName#>">
            </ExternalTableInput>
            <Inputs>
            <# foreach (var column in table.Columns) { #>
                <Column SourceColumn="<#=column.Name#>" TargetColumn="<#=column.Name#>" />
            <# } #>
            </Inputs>
        <Outputs>
            <# foreach (var column in table.Columns) { #>
            <Column SourceColumn="<#=column.Name#>" TargetColumn="<#=column.Name#>" />
            <# } #>
        </Outputs>
    </Lookup>
    <# } #>
        <OleDbDestination Name="Load" ConnectionName="Source" UseFastLoadIfAvailable="false">
            <InputPath OutputPathName="LKP_<#=table.Name#>.Match" />
            <ExternalTableOutput Table="<#=table.SchemaQualifiedName#>" />
        </OleDbDestination>
    </Transformations>
</Dataflow>

您没有提供 biml，因此很难诊断问题，但这是一个带有两个查找的工作示例
