  • 项目

Removes invalid IDTSInputColumn90 objects from an IDTSInputColumnCollection90.

命名空间: Microsoft.SqlServer.Dts.Pipeline.Wrapper
程序集: Microsoft.SqlServer.DTSPipelineWrap (in microsoft.sqlserver.dtspipelinewrap.dll)

语法

声明
<DispIdAttribute(115)> _
Sub RemoveInvalidInputColumns

[DispIdAttribute(115)] 
void RemoveInvalidInputColumns ()

[DispIdAttribute(115)] 
void RemoveInvalidInputColumns ()

/** @attribute DispIdAttribute(115) */ 
void RemoveInvalidInputColumns ()

DispIdAttribute(115) 
function RemoveInvalidInputColumns ()

备注

This method removes the IDTSInputColumn90 columns whose LineageID property does not match the LineageID property of a column in the IDTSVirtualInput90 of the IDTSInput90.

A component could perform this work directly by calling the GetVirtualInput method of each of the input objects in its InputCollection and then checking each column in the IDTSVirtualInputColumnCollection90 against those in the IDTSInputColumnCollection90.
