Question

Suppose we have 3 employees in each department.we have total 3 departments . Below is the sample source table

Emp deptno salary
A    10     1000
B    10              


        

Answer 1

You can find 2nd highest salary something like this:

select max(a.Salary),a.Deptno from Employee a join (select MAX(salary) salary 
from Employee group by Deptno) b on a.Salary < b.salary group by a.Deptno

And no MAX() is not an analytic function.
