   parameter.SourceColumn = "Description"  
   parameter.SourceVersion = DataRowVersion.Current

End Sub

public void CreateOracleParameter()   
{  
   OracleParameter parameter = new OracleParameter("pDName", OracleType.VarChar);

This property is set to the version of the DataRow used by the DataRow.Item[] property (DataRow indexer), or the DataRow.GetChildRows method of the DataRow object.
