So, what are you waiting for, let's first check the problem, and then we'll write an SQL query using SELF Join to solve this problem.

Write an SQL Query to Find Employees Earning More Than Managers
The Employee table holds all employees including their managers. Every employee has an Id, and there is also a column for the manager Id as shown below:

+----+-------+--------+-----------+
| Id | Name  | Salary | ManagerId |
+----+-------+--------+-----------+
| 1  | Joe   | 70000  | 3         |
| 2  | Henry | 80000  | 4         |
| 3  | Sam   | 60000  | NULL      |
| 4  | Max   | 90000  | NULL      |
+----+-------+--------+-----------+

Given the Employee table, write a SQL query that finds out employees who earn more than their managers. For the above table, Joe is the only employee who earns more than his manager because Henry's Manager is Max who earns 90000 which is more than Henry's salary of 80000.
