Assembly:  Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)

Syntax

'Declaration
Function MapOutputColumn ( _
    lOutputID As Integer, _
    lOutputColumnID As Integer, _
    lExternalMetadataColumnID As Integer, _
    bMatch As Boolean _
) As IDTSExternalMetadataColumn100
'Usage
Dim instance As IDTSDesigntimeComponent100 
Dim lOutputID As Integer 
Dim lOutputColumnID As Integer 
Dim lExternalMetadataColumnID As Integer 
Dim bMatch As Boolean 
Dim returnValue As IDTSExternalMetadataColumn100

abstract MapOutputColumn : 
        lOutputID:int * 
        lOutputColumnID:int * 
        lExternalMetadataColumnID:int * 
        bMatch:bool -> IDTSExternalMetadataColumn100
function MapOutputColumn(
    lOutputID : int, 
    lOutputColumnID : int, 
    lExternalMetadataColumnID : int, 
    bMatch : boolean
) : IDTSExternalMetadataColumn100

Parameters

  • bMatch
    Type: System.Boolean
    Indicates whether the output column and external metadata columns match.

Return Value

Type: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 that is mapped to the output column.

Remarks

This method is called to map an output column to a column in the ExternalMetadataColumnCollection of the output. When you are developing a custom data flow component, you override this method, to ensure that the external columns and the output column match, and to indicate that you want to allow the mapping to occur. For more information about working with external metadata columns, see Implementing External Metadata.
