MySQL: select random rows, but without duplicates

[eluser]codex[/eluser]
Is it possible to select random rows, but without duplicates? Something like this :

(Obviously pseudocode)

Code:

SELECT object_id
FROM objects
ORDER BY RAND()
BUT UNIQUE(object_id)
LIMIT 0, 12

i think you can do it with distinct !

Code:

SELECT distinct object_id
FROM objects
ORDER BY RAND()
LIMIT 0, 12

I know, and I was under the impression that I tried that and it failed. But I guess I was somewhere else with my thoughts, because DISTINCT does the trick. So thanks :-)
