template <class T, class RowClass = CSimpleRow>
class ATL_NO_VTABLE IRowsetIdentityImpl

RowClass
The storage unit for the HROW.

Header: atldb.h

Compares two row handles to see if they refer to the same row.

STDMETHOD(IsSameRow )(HROW hThisRow,
   HROW hThatRow);

See IRowsetIdentity::IsSameRow in the OLE DB Programmer's Reference.

To compare row handles, this method casts the HROW handles to RowClass members and calls memcmp on the pointers.
