As this is tagged with sql only  the following is using ANSI SQL and a window function   select id  game  point from     select id  game  point            row number   over  partition by game order by point  as rn   from games   t where rn   1

This is another way of doing the same thing  which would allow you to do interesting things like select the top 5 winning games  etc     SELECT    FROM         SELECT ROW NUMBER   OVER  PARTITION BY ID ORDER BY Point  as RowNum         FROM Table    X   WHERE RowNum   1   You can now correctly get the actual row that was identified as the one with the lowest score and you can modify the ordering function to use multiple criteria  such as  Show me the earliest game which had the smallest score   etc

This alternative approach uses SQL Server s OUTER APPLY clause  This way  it   creates the distinct list of games  and fetches and outputs the record with the lowest point number for that game    The OUTER APPLY clause can be imagined as a LEFT JOIN  but with the advantage that you can use values of the main query as parameters in the subquery  here  game    SELECT colMinPointID FROM     SELECT game   FROM table   GROUP BY game   As rstOuter OUTER APPLY     SELECT TOP 1 id As colMinPointID   FROM table As rstInner   WHERE rstInner game   rstOuter game   ORDER BY points   AS rstMinPoints
