Try
rm.exec('SELECT d.name depname, e.name empname, e.payment payment, e.bonus bonus, e.age age FROM employee e, department d where d.id = e.depid order by age desc')

Open in new window

rm.exec('SELECT d.name depname, e.name empname, e.payment, e.bonus FROM employee e, department d where d.id = e.depid order by e.age desc')
