语法
声明
Public Overridable Function MapOutputColumn ( _
lOutputID As Integer, _
lOutputColumnID As Integer, _
lExternalMetadataColumnID As Integer, _
bMatch As Boolean _
) As IDTSExternalMetadataColumn100
用法
Dim instance As CManagedComponentWrapperClass
Dim lOutputID As Integer
Dim lOutputColumnID As Integer
Dim lExternalMetadataColumnID As Integer
Dim bMatch As Boolean
Dim returnValue As IDTSExternalMetadataColumn100
returnValue = instance.MapOutputColumn(lOutputID, _
lOutputColumnID, lExternalMetadataColumnID, _
bMatch)
public virtual IDTSExternalMetadataColumn100 MapOutputColumn(
int lOutputID,

public:
virtual IDTSExternalMetadataColumn100^ MapOutputColumn(

abstract MapOutputColumn :

public function MapOutputColumn(
lOutputID : int,
lOutputColumnID : int,
lExternalMetadataColumnID : int,
bMatch : boolean
) : IDTSExternalMetadataColumn100
参数
- lOutputID
类型：System.Int32
The ID of the IDTSOutput100 object.
- lOutputColumnID
类型：System.Int32
The ID of the IDTSOutputColumn100 object.
- lExternalMetadataColumnID
类型：System.Int32
The ID of the IDTSExternalMetadataColumn100 object.
- bMatch
类型：System.Boolean
Specifies whether the IDTSOutputColumn100 column should be set to match the IDTSExternalMetadataColumn100 column.
返回值
类型：Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 that is mapped to the output column.
实现
IDTSDesigntimeComponent100.MapOutputColumn(Int32, Int32, Int32, Boolean)
注释
Call this method to map an IDTSOutputColumn100 column to a column in the ExternalMetadataColumnCollection of the output. If the bMatch parameter is true, and the data type properties of the two columns differ, the component will modify the data type properties of the output column to match the properties of the external metadata columns.
