Table

Where Name+Age+ID together represents one individual person. I want to get the the rows where each student gets the highest score in shortest amount of time.

Output

I tried this following sql but it doesn't work:

SELECT TOP 1 * FROM STUDENTMARKS GROUP BY Name, Age, ID ORDER BY Score DESC, Time ASC

select *,row_number() over(partition by name, age, id order by score desc, time asc) as rn
from STUDENTMARKS
)A where rn=1
