(SELECT MAX(salary) 
FROM employees 
WHERE salary < 
(SELECT MAX(salary)

101		Neena		Kochhar		NKOCHHAR515.123.4568	2005-09-21	AD_VP	17000.00	0.00	100		90

Code Explanation:

The said query in SQL that retrieves all columns (denoted by *) from the employees table where the employee ID matches the employee ID of the second highest salary in the employees table. The first subquery in the IN clause calculates the maximum salary in the employees table, and the second subquery calculates the second highest salary by finding the maximum salary in the employees table while excluding the highest salary.
The result of the second subquery is then used to find the employee ID(s) of the second highest salary in the main query by matching the salary.
The final result of the query will be all the employees who have the second highest salary in the employees table.
