employee may be managed by another employee. To denote an
employee‘s manager, the employee_id of the manager is entered into
the manager_id field of the employee reporting to that manager. In
order to produce a list of which managers supervise which employees,
the table may be joined to itself using these two attributes
(employee_id, manager_id). This is known as a SELF-JOIN. Use a
SELF-JOIN on the employees table to produce a result containing two
columns: the concatenated last_name and first_name of the manager,
and the concatenated last_name and first_name of the employee.
Label the first-column supervisor, and the second-column employee.
