how to alter several users

Hello,

I can change quota for one user (alter user foo quota 1M on users;), but is it possible to alter several users in one query, for example, those I can retrieve in the following one :

select GRANTEE from DBA_ROLE_PRIVS where GRANTED_ROLE = 'TOTO';

I think yes, but I don't know the syntax.

I'm on oracle 8.0.5

Regards
