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 | +----------+
解决方案如下：
# Write your MySQL query statement below Select a.Name as Employee from Employee a inner join Employee b on a.ManagerId=b.Id where a.Salary>b.Salary开始对sql感兴趣了~
