Hello guys, if you have attended programming or software development interview then you may have come across SQL queries. In the past, I have shared popular SQL queries from interviews and one of them is how to find the 2nd highest salary of employee in SQL. This is probably the most popular SQL query question I have come across in my career and I have seen it many times. When I first come across this one I have hard time to solve it but over the years, I have learned several ways to solve this problem and find the 2nd highest or even 3rd highest salary in SQL. Earlier, I have shared how to find Nth highest salary and in this article, I am going to share 5 different ways to find the second highest salary in SQL.
