над его строкой rn = 1

Я хочу отфильтровать rn = max(rn)

Answer 1

Измените order by ox asc на order by ox desc и используйте rn = 1

select  *
from    (
        select  *
        ,       row_number() over (partition by name order by ox desc) as rn
        from    YourTable
        ) as SubQueryAlias
where   rn = 1

Answer 2

Отметьте это, чтобы получить rn = max (rn):

select top 1 * from 
( select * , 
    row_number() over (partition by name order by ox asc) 
    as rn from YourTable ) 
as SubQueryAlias 
order by rn desc
