Assignment (Excercise #1)
I am sorry but I did not get what is meant by 'disregard the department the managers have worked in'
I firstly got that we are required to get the last department each manager is working in so my solution was
SELECT
emp_no, dept_no, max(from_date),
row_number() over (order by emp_no) as row_num
FROM
dept_manager
GROUP BY dept_no;
while the excercise solution is not like that
