A row handle is logically a unique tag for a result row. IRowsetImpl creates a new CSimpleRow for every row requested in IRowsetImpl::GetNextRows. CSimpleRow can also be replaced with your own implementation of the row handle, as it is a default template argument to IRowsetImpl. The only requirement to replacing this class is to have the replacement class provide a constructor that accepts a single parameter of type LONG.
