Hinweise

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.
