在Have子句中使用MIN函数 [英] Using the MIN function in the having clause

问题描述

我想知道最低薪水的雇员的名字.有一种方法可以仅使用一个查询来执行此操作吗?我在下面给出了我的查询，该查询不起作用，因为hading子句需要一个条件.有什么办法可以在hading子句中给出一个条件，以最低的工资重新获得员工的姓名吗?

I want to get the name of the employee who has the minimum salary. Is there a way to do this using only one query? I have given my query below, it doesn't work because the having clause requires a condition. Is there any way to give a condition in the having clause that will retreive the employee name with the minimum salary?

SELECT first_name,min(salary) as "sal"
FROM Employees
GROUP BY first_name 
having min(salary);

推荐答案

如何使用ROWNUM?

SELECT *
FROM(SELECT first_name, salary
     FROM Employees
     ORDER BY salary
) WHERE ROWNUM = 1
