Top 10 MYSql i inne łącznie

Dla przypomnienia, zgadzam się z komentarzem @DamienBlack, jednak jeśli należało to zrobić w jednym zapytaniu a UNION ALL może załatwić sprawę:

(
  SELECT VENDOR_fullname as name, SUM(POTENTIAL_RECOVERY) as recovery
  FROM COMPLETE
  GROUP BY VENDOR_fullname
  ORDER BY SUM(POTENTIAL_RECOVERY) DESC
  LIMIT 10
)
UNION ALL
(
  SELECT 'All others' as name, SUM(subtotal) as recovery
  FROM 
  (
    SELECT SUM(POTENTIAL_RECOVERY)
    FROM COMPLETE
    GROUP BY VENDOR_fullname
    ORDER BY SUM(POTENTIAL_RECOVERY) DESC
    LIMIT 10, 18446744073709551615
  ) as subtotal;
)
