grants_to_roles

You can view the privileges granted to user-defined roles by querying the view grants_to_roles.

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 grants_to_roles:

Field	Description
GRANTEE	The role to whom this privilege is granted. Only user-defined roles will be listed in this view, and system-defined ones will not.
OBJECT_CATALOG	The catalog to which the object belongs. NULL is returned if the privilege is a SYSTEM, RESOURCE GROUP, RESOURCE, USER, or GLOBAL FUNCTION level privilege.
OBJECT_DATABASE	The database to which the object belongs. NULL is returned if the privilege is a SYSTEM, RESOURCE GROUP, RESOURCE, USER, GLOBAL FUNCTION, or CATALOG level privilege.
OBJECT_NAME	The table to which the object belongs. NULL is returned if the privilege is a SYSTEM, RESOURCE GROUP, RESOURCE, USER, GLOBAL FUNCTION, CATALOG, or DATABASE level privilege.
OBJECT_TYPE	The type of the object.
PRIVILEGE_TYPE	The type of the privilege. Different privileges on the same object will be merged and returned in a single row. As shown in the following example, role_test has the SELECT and ALTER privileges on default_catalog.db_test.tbl1.
IS_GRANTABLE	Whether the grantee has the grant option.
