{0C733ABD-2A1C-11CE-ADE5-00AA0044773D}

IRowsetCurrentIndex is the interface for determining and selecting a specific index for a rowset. This is limited to rowsets that expose IRowsetIndex. IRowsetCurrentIndex provides a mechanism for providers to reorder their rows without reopening the rowset. This interface can be effective for both integrated and nonintegrated indexes. For a complete description of indexes, see Chapter 10: Index Rowsets and Chapter 11: Integrated Indexes.
