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

Here I used two queries for the following scenarios which are asked during an interview
First scenario:
Find all second highest salary in the table (Second highest salary with more than one employee )

select * from emp where salary
   In (select MAX(salary) from emp where salary NOT IN (Select MAX(salary) from 
   emp));

Second scenario:
Find only the second highest salary in the table

select min(temp.salary) from (select * from emp order by salary desc limit 2) 
  temp;
