Namespace:  Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly:  Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)

Syntax

'Declaration
Public Enumeration DTSUsageType
'Usage
Dim instance As DTSUsageType

public enum DTSUsageType

public enum class DTSUsageType

type DTSUsageType

public enum DTSUsageType

Members

	Member name	Description
	UT_READONLY	The component will read the values of an input column, but will not modify them.
	UT_READWRITE	The component will read and write to the column data.
	UT_IGNORED	The column is ignored by the component.

Remarks

This enumeration contains values that indicate how a component will use an IDTSInputColumn100 object.

Components validate that each column in their IDTSInputColumnCollection100 has its UsageType property set correctly.

For example, if a component needs read/write permission to an input column and the column's UsageType property is set to UT_READONLY, it should post a DTS_E_CANTSETUSAGETYPE message and return a failure result from Validate.
