Answer 1

You can use a window function :

select top (1) with ties t.*
from (select t.*, count(*) over (partition by dept) as cnt
      from table t
     ) t
order by rank() over (order by cnt desc), dept;

Answer 2

please try this code

SELECT emp_id, dept,count(*) OVER (PARTITION by dept)
FROM table
ORDER BY count(*) OVER (PARTITION by dept) desc, 
emp_id
