Can you list the driver ids and whether they drive full time or not?
select driver_id, if_full_time from school_bus
Hmm, I also want to know their years working.
select driver_id, years_working, if_full_time from school_bus
Can you tell me the name of the driver who is driving the school bus with the longest working history?
select t1.name from driver as t1 join school_bus as t2 on t1.driver_id = t2.driver_id order by years_working desc limit 1
