SQL med rang og partition

Hvis feld1 er unik i feld0 partitioner, kan du:

select  *
,       (
        select  count(*)
        from    YourTable yt2
        where   yt2.feld0 = yt1.feld0 -- Same partition
                and yt2.feld1 <= yt1.feld1 -- Lower or equal rank
        ) as ranking
from    YourTable yt1
