   parameter.IsNullable = True  
   parameter.SourceColumn = "Description"  
   parameter.SourceVersion = DataRowVersion.Current  
   parameter.Direction = ParameterDirection.Output  
End Sub

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

This property is used by the UpdateCommand during the DbDataAdapter.Update to determine whether the original or current value is used for a parameter value. This lets primary keys be updated. 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.
