--- toc_priority: 52 toc_title: SET ROLE --- # SET ROLE Statement {#set-role-statement} Activates roles for the current user. ``` sql SET ROLE {DEFAULT | NONE | role [,...] | ALL | ALL EXCEPT role [,...]} ``` ## SET DEFAULT ROLE {#set-default-role-statement} Sets default roles to a user. Default roles are automatically activated at user login. You can set as default only the previously granted roles. If the role isn’t granted to a user, ClickHouse throws an exception. ``` sql SET DEFAULT ROLE {NONE | role [,...] | ALL | ALL EXCEPT role [,...]} TO {user|CURRENT_USER} [,...] ``` ## Examples {#set-default-role-examples} Set multiple default roles to a user: ``` sql SET DEFAULT ROLE role1, role2, ... TO user ``` Set all the granted roles as default to a user: ``` sql SET DEFAULT ROLE ALL TO user ``` Purge default roles from a user: ``` sql SET DEFAULT ROLE NONE TO user ``` Set all the granted roles as default excepting some of them: ``` sql SET DEFAULT ROLE ALL EXCEPT role1, role2 TO user ```
