SQL Server Co-related Query – Select the second highest

This a good example of the co-related query.

For example we have table with 5 employees and their salary.


If we want to query the employee with second highest salary, we can use the query below.

SELECT * FROM Employee e1
WHERE 2 = ( SELECT COUNT(*) FROM Employee e2
WHERE e2.EmployeeSalary >= e1.EmployeeSalary );
