CAN RETURN WRONG RESULT SET PROBLEM ------- In ha_partition::cmp_ref() we were only calling the underlying cmp_ref() of storage engine if the records are in the same partiton,else we sort by partition and returns the result.But the index merge intersect algorithm expects first to sort by row-id first and then by partition id. FIX --- Compare the refernces first using storage engine cmp_ref and then if references are equal(only happens if non clustered index is used) then sort it by partition id.
