Bagaimana cara menambahkan nomor urut untuk grup dalam kueri SQL tanpa tabel temp

Contoh data

create table sometable([group] varchar(10), id int, somedata int)
insert sometable select 'Horses', 9, 11
insert sometable select 'chickens', 19, 121
insert sometable select 'Horses', 29, 123
insert sometable select 'chickens', 49, 124
insert sometable select 'Cows', 98, 1
insert sometable select 'Horses', 99, 2

Kueri

select
    Record = ROW_NUMBER() over (order by [Group], id),
    [Group],
    GroupSequence = DENSE_RANK() over (order by [Group])
from sometable

Keluaran
