Assembly: Microsoft.SqlServer.DTSPipelineWrap (in microsoft.sqlserver.dtspipelinewrap.dll)

Syntax

'Declaration
Public Enumeration DTSUsageType

public enum DTSUsageType

public enum class DTSUsageType

public enum DTSUsageType

public enum DTSUsageType

Members

Member name	Description
UT_IGNORED	The column is ignored by the component.
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.

Remarks

This enumeration contains values that indicate how a component will use an IDTSInputColumn90 object.

Components validate that each column in their IDTSInputColumnCollection90 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.
