För ordens skull håller jag med @DamienBlacks kommentar, dock om det måste göras i en fråga en UNION ALL
skulle kunna göra susen:
(
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;
)
