role_edges

You can view the grantees of roles by querying the view role_edges.

note

By default, only users or roles with the user_admin role can access this view. You can grant other users the SELECT privilege on this view using GRANT.

The following fields are provided in role_edges:

FieldDescription
FROM_ROLEThe role that is granted. Multiple records with the same FROM_ROLE can be returned because a role can be granted to multiple roles and users.
TO_ROLEThe role to whom the current FROM_ROLE is granted. NULL is returned if the current FROM_ROLE is granted to a user.
TO_USERThe user to whom the current FROM_ROLE is granted. NULL is returned if the current FROM_ROLE is granted to a role.

Example:

MySQL > SELECT * FROM sys.role_edges;
+------------+------------+---------------+
| FROM_ROLE  | TO_ROLE    | TO_USER       |
+------------+------------+---------------+
| dba_leader | director   | NULL          |
| dba        | dba_leader | NULL          |
| dba        | NULL       | 'aneesh'@'%'  |
| dba        | NULL       | 'chelsea'@'%' |
| dba_leader | NULL       | 'albert'@'%'  |
| director   | NULL       | 'stan'@'%'    |
| root       | NULL       | 'root'@'%'    |
+------------+------------+---------------+
