Explanation:

The said query in SQL that retrieves the five employees with the lowest salaries in the company from the 'employees' table.

The subquery in the WHERE clause that counts the number of employees who have a higher salary than the current employee being evaluated is used to limit the results to only the five employees with the lowest salaries.

The outer SELECT statement then returns the information for the employees with the five employees with the lowest salaries.
