If you want the unique rows, use distinct. If you want the highest score
per person, you'll have to use group by with an aggregate function ;)

SELECT name, max(score)
FROM table
GROUP BY name
ORDER BY score DESC
LIMIT 0,3

lets say I have this data

id   name   score
1   dude1     9.1
2   dude2   9.5
3   dudette1 9.0
4   dude1    9.3
5  dudette1 8.5

And I want to select highest 3 scores:

SELECT score FROM table ORDER BY score DESC LIMIT 0,3

result will be

9.5
9.3
9.1

but how can I select both the name and the score and I only want one
score per person

I can do: SELECT DISTINCT name FROM table ORDER BY score DESC LIMIT 0,3
this will give me the correct names in the correct order, but I want
their score also

is this possible in one query ?


thanksuwel !
