    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      |    +----------+    自串連        select e.name as 'Employee'             from Employee e,Employee m                 where e.managerid=m.id                     and                        e.salary>m.salary;    內串連        select e.name as Employee             from employee e inner join employee m                 on e.managerid=m.id and e.salary>m.salary;
