如何从员工表中删除收入最高的员工？

Question

Employee 表由Employee_id，雇员姓名和薪水组成

如何从员工表中删除收入最高的员工？ 我尝试过

delete from employee
where salary = (select max(salary) from employee);

但是它给出了一个错误；

  

错误代码：1093。您不能指定目标表'employee'进行更新   在FROM子句中0.0022秒

Answer 1

您只需完成

delete from employee 
order by salary desc
limit 1

或者修正您的查询

delete from employee 
where salary in 
(
  select * from (select max(salary) from employee) x
)

因为您需要构建临时表作为解决方法，因为您需要在同一表中进行选择并删除。

Answer 2

把它埋得更深

delete from employee 
where salary = (select maxsalary from (select max(salary) maxsalary from employee) s );

这将删除所有具有最高薪水的员工

Answer 3

这应该做。

delete from employee where salary = (select max(salary) from employee);
