原题如下:
Write a SQL query to get the second highest salary from the Employee
table.
+----+--------+ | Id | Salary | +----+--------+ | 1 | 100 | | 2 | 200 | | 3 | 300 | +----+--------+
For example, given the above Employee table, the second highest salary is 200
. If there
is no second highest salary, then the query should return null
.
解决方案如下:
# Write your MySQL query statement below select max(Salary) from Employee where Salary<(select max(Salary) from Employee )
思路是先查出工资最高的,然后再查剩下的人里面工资最高的,就是第二高的了~
