Method 1 Using ORDER BY and LIMIT Clause One way to find the second highest salary is by using the ORDER BY and LIMIT clause Here is the SQL query SELECT DISTINCT Salary FROM Employee ORDER BY Salary DESC LIMIT 1 OFFSET 1 This query retrieves all unique salaries from the Employee table orders them in descending order skips the To use NTH VALUE we have to specify the column and the value of N Since we want to get the third highest salary the column is salary and N 3 hence we have NTH VALUE salary 3 This will get us the third highest salary For a window function to work we need to use an OVER clause
Output Now to find the second highest salary we nest the above query into another query as written below SELECT MAX SALARY FROM Employee WHERE SALARY SELECT MAX SALARY FROM Employee This query will give you the desired output i e 12000 which is the second highest salary The query selects the maximum salary from the Employee table using the MAX function and names it Second Highest Salary The WHERE clause filters the rows where the salary is less than the maximum salary from the subquery which gives the highest salary This effectively retrieves the second highest salary from the Employee table

SELECT salary RANK OVER ORDER BY salary DESC as rank FROM employee sub WHERE rank 2 And if you want to find the 3rd 4th or 5th highest salary in SQL you can use the same logic which I have also explained in my earlier post about SQL query to find the Nth highest salary Step 1 Create a Database Open your SQL Server and use the following script to create the chittadb Database Create database chittadb Now select the script query then press F5 or click on the Execute button to execute the above script You should see a message Command s completed successfully
Maybe this will also help you to understand Try running the query for where 0 it will return the highest salary because none of the employees have a higher salary than the highest one Alternatively you can keep the 2 but change the e1 salary e2 salary condition to e1 salary e2 salary to produce the correct result i e like this We can simply use the Max function as shown below Select Max Salary from Employee To get the second highest salary use a subquery along with Max function as shown below Select Max Salary from Employee where Salary Select Max Salary from Employee This query gives an incorrect result in the case of 3 rd highest salary
