Syntax

'Declaration
Function MapOutputColumn ( _
    lOutputID As Integer, _
    lOutputColumnID As Integer, _

'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

    int lOutputID,
    int lOutputColumnID,
    int lExternalMetadataColumnID,
    bool bMatch
)

IDTSExternalMetadataColumn100^ MapOutputColumn(
    [InAttribute] int lOutputID, 
    [InAttribute] int lOutputColumnID, 
    [InAttribute] int lExternalMetadataColumnID, 
    [InAttribute] bool bMatch
)

abstract MapOutputColumn : 
        lOutputID:int * 
        lOutputColumnID:int * 
        lExternalMetadataColumnID:int * 
        bMatch:bool -> IDTSExternalMetadataColumn100 

function MapOutputColumn(
    lOutputID : int, 
    lOutputColumnID : int, 
    lExternalMetadataColumnID : int, 
    bMatch : boolean
) : IDTSExternalMetadataColumn100

Parameters

• lOutputID
  Type: System.Int32
  The ID of the IDTSOutput100 object.

• lOutputColumnID
  Type: System.Int32
  The ID of the IDTSOutputColumn100 object.

• lExternalMetadataColumnID
  Type: System.Int32
  The ID of the IDTSExternalMetadataColumn100 object that is linked to the output column.

• 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.
