定义

命名空间:
Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012
程序集:
Microsoft.SqlServer.DTSPipelineWrap.dll
public:
 Microsoft::SqlServer::Dts::Pipeline::Wrapper::Sql2012::IDTSInputColumn100 ^ SetUsageType(int lInputID, Microsoft::SqlServer::Dts::Pipeline::Wrapper::Sql2012::IDTSVirtualInput100 ^ pIDTSVirtualInputObject, int lLineageID, Microsoft::SqlServer::Dts::Pipeline::Wrapper::Sql2012::DTSUsageType eUsageType);
[System.Runtime.InteropServices.DispId(16)]
public Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012.IDTSInputColumn100 SetUsageType (int lInputID, Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012.IDTSVirtualInput100 pIDTSVirtualInputObject, int lLineageID, Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012.DTSUsageType eUsageType);
[<System.Runtime.InteropServices.DispId(16)>]
abstract member SetUsageType : int * Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012.IDTSVirtualInput100 * int * Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012.DTSUsageType -> Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2012.IDTSInputColumn100
Public Function SetUsageType (lInputID As Integer, pIDTSVirtualInputObject As IDTSVirtualInput100, lLineageID As Integer, eUsageType As DTSUsageType) As IDTSInputColumn100

参数

lInputID
Int32
pIDTSVirtualInputObject
IDTSVirtualInput100
lLineageID
Int32
eUsageType
DTSUsageType

返回

IDTSInputColumn100

设置了 UsageType 的 IDTSInputColumn100 对象。

属性
DispIdAttribute

注解

当为组件选择 IDTSVirtualInputColumnCollection100 中的列时，将调用 SetUsageType。 usageType如果UT_READONLY或UT_READWRITE，则会为组件创建新的输入列，该列反映参数lLineageID指定的 IDTSVirtualInputColumn100。 如果 usageType UT_IGNORED且集合中存在该列，则删除该列并返回 null 。
