OLE DB Interfaces
IRowsetLocate is the interface for fetching arbitrary rows of a rowset. A rowset that does not implement this interface is a sequential rowset. IRowsetLocate is a prerequisite for IRowsetScroll.
When IRowsetLocate or one of its direct descendants is present on a rowset, column 0 is the bookmark for the rows. Reading this column will obtain a bookmark value that can be used to reposition to the same row.
IRowsetLocate is an optional interface on the rowset object. However, general consumers expect the rowset object to implement this interface, either natively or via OLE DB Services.
