Employees Earning More Than Their Managers
Problem:
The Employee table holds all employees including their managers.
Every employee has an Id, and there is also a column for the manager Id.
+----+-------+--------+-----------+
| 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.
+----------+
| Employee |
+----------+
| Joe |

- Analysis:
SELECT p.Name AS Employee
FROM Employee AS p INNER JOIN ON Employee AS q ON p.ManagerId=q.Id AND p.Salary > q.Salary
- SQL:
# Write your MySQL query statement below
SELECT p.Name AS Employee FROM Employee AS p INNER JOIN Employee AS q ON p.ManagerId = q.Id AND p.Salary > q.Salary
