Then we might as well add Bram too, no? We can ask - but we might want to warn them about the huge amount of spam created here. By me, mainly. Cheers! Lieven Sterck wrote:

Hey .. o_O .. what ?
But that would make Francis Marijn 'the buffer underflow'? (wait, Marijn[-1] in perl would just give the last element .. which is Marijn .. so Marijn = Francis, which makes me Francis the second, which actualy makes sense!)
Should I now also explain the drawback of loosing the ability of using indexes with group by for extra points ? Or ain't this a priority queue?

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

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 !
