DE clausule GEBRUIKEN in orakel 11g

Nee, je kunt niet zomaar ON vervangen met USING . Maar u kunt de query herschrijven zodat deze USING . bevat clausule in joins. Zie de juiste syntaxis hieronder:

select e.employee_id,
       e.last_name,
       department_id, --Note there is no table prefix
       d.department_name,
       l.city,
       location_id --Note there is no table prefix
  from employees e
  join departments d
 using (department_id)
  join locations l
 using (location_id)
 where e.manager_id = 149;
