Roles

Role management and role proxy permissions use the following modelled hierarchy:

Roles > role

Synopsis

ALL ROLES
```
GRANT <permission>[, <permission> ...]
ON ALL ROLES
TO <role_name>;
```
where permission values are ALL PERMISSIONS, ALTER, AUTHORIZE, CREATE, DESCRIBE, and DROP
ROLE
```
GRANT <permission>[, <permission> ...]
ON ROLE <role_name>
TO <role_name>;
```
where permission values are ALL PERMISSIONS, ALTER, AUTHORIZE, CREATE, DESCRIBE, and DROP
Role as a permission set (applies if Role Manager mode: internal)
```
GRANT <role_name>
TO <role_name>;
```
Nesting roles gives all the permissions of the first role in the statement to the second. With internal role management, use permission set roles to create your own hierarchical permissions structures.
