Needing some help about robots.txt

[french dread]

I have a website with some urls like these, used to track partnership's referals : www.website.com/?refererId=10

The problem is that Google indexed those urls and it could mess up statistics by couting "fake" hits from Google. I think it is possible to exclude inclusion via robots.txt but dont know what syntax use, as it is not a directory.

How to proceed? can I use dynamic urls in robots txt like :

Disallow: /?refererId=1
Disallow: /?refererId=2
(...)
Disallow: /?refererId=10

thanks for the help

I think:

Disallow: /?


is all you need. Not real sure about that however. :)
