How to get second-highest salary employees in a table

Question

It\'s a question I got this afternoon:

There a table contains ID, Name, and Salary of Employees, get names of the second-highest salary employees, in SQL Server

Answer 1

Can we also use

select e2.max(sal), e2.name
from emp e2
where (e2.sal <(Select max (Salary) from empo el))
group by e2.name

Please let me know what is wrong with this approach
