Parameter Description

Role name;specifying anything other than RDB$ADMIN will fail

sys_privilege

System privilege to grant

ALTER ROLE can be used to grant or revoke system privileges from a role, or enable and disable the capability for Windows Administrators to assume administrator privileges automatically when logging in.

This last capability can affect only one role: the system-generated role RDB$ADMIN.

For details on auto admin mapping, see AUTO ADMIN MAPPING.

It is not possible to selectively grant or revoke system privileges.Only the privileges listed in the SET SYSTEM PRIVILEGES clause will be available to the role after commit, and DROP SYSTEM PRIVILEGES will remove all system privileges from this role.
