Locates the input for the column of the host.
命名空间: Microsoft.SqlServer.Dts.Pipeline
程序集: Microsoft.SqlServer.PipelineHost(在 Microsoft.SqlServer.PipelineHost.dll 中)
语法
声明
Public Function HostMapInputColumn ( _
wrapper As IDTSManagedComponentWrapper100, _
iInputID As Integer, _
iInputColumnID As Integer, _
iExternalMetadataColumnID As Integer _
) As IDTSExternalMetadataColumn100
用法
Dim instance As ManagedComponentHost
Dim wrapper As IDTSManagedComponentWrapper100
Dim iInputID As Integer
Dim iInputColumnID As Integer
Dim iExternalMetadataColumnID As Integer
Dim returnValue As IDTSExternalMetadataColumn100
returnValue = instance.HostMapInputColumn(wrapper, _
iInputID, iInputColumnID, iExternalMetadataColumnID)
