Question

I need help with an advanced SQL-query (MSSQL 2000).

I have a table called Result that lists athletics 100 meter race-times. A runner can have several racetimes but I want to show only the best time from each runner.

The Result-table contains three columns, Result_id, athlete_id, result_time. So athlete_id must be unique when I list the values and result_time must be the fastest (lowest) value.

Any ideas?

Answer 1

If you simply need the fastest time for each athlete_id, do this:

select athelete_id, min(result_time) as FastestTime
from result
group by athelete_id

To show additional columns from the result table, you can join back to it like this:

select r.*
from result r
inner join (
    select athelete_id, min(result_time) as FastestTime
    from result
    group by athelete_id
) rm on r.athelete_id = rm.athelete_id and r.result_time = rm.FastestTime
