It is impossible with one SQL query, as you should update 100 different tables with 100 different names. So you should write script for that.
What WordPress version do you use? If you upgrade to the lastest WordPress 3.0.5 multi-site you can use User Role Editor plugin then. It mights update roles for all sites of the mulit-site network simultaneously.

Hi Mel!
I think this SQL command could help you
insert into wp_usermeta (user_id, meta_key, meta_value)
select wp_users.id, 'wp_1_capabilities' as meta_key, 'a:1:{s:11:”contributor”;b:1;}' as meta_value from wp_users where wp_users.id!=1

I have a dilemma. I migrated users from a database to my wordpress mu database but for some users field wp_1_capabilites is missing in wp_usermeta table. How can I mass add this field for all users with Contributor capabilities?
