DTSUsageType Enumeration


Indicates how an IDTSInputColumn100 object is used by a component.

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

public enum DTSUsageType

Member nameDescription

The column is ignored by the component.


The component will read the values of an input column, but will not modify them.


The component will read and write to the column data.

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.
