How to find maximum avg

Question

I am trying to display the maximum average salary; however, I can\'t seem to get it to work.

I can get a list of the average salaries to display with:

Answer 1

select worker_id, avgsal 
from 
(
  select worker_id, avg(salary) as avgsal 
  from workers 
  group by worker_id
) 
where avgsal=(select  max(avgsal) 
              from (select worker_id, avg(salary) as avgsal 
                    from workers group by worker_id))

This will display the highest average along with worker id
