Sql Oracle在一个查询中显示最小值（），最大值（）

我有一张桌子-- 工作单位名称、员工名称、工资

我希望结果显示每个雇主的最低和最高工资组，请参见下文

工作

有什么想法吗？非常感谢

干杯，

本，这个怎么样？这不完全是你要求的，但应该做得很好：

SELECT w.*,
    (SELECT employee_name FROM works WHERE employer_name = w.Employer AND salary = w.Min AND ROWNUM <= 1) AS EmployeeMin,
    (SELECT employee_name FROM works WHERE employer_name = w.Employer AND salary = w.Max AND ROWNUM <= 1) AS EmployeeMax
FROM (
    SELECT employer_name AS Employer,
        min(salary) AS Min,
        max(salary) AS Max
    FROM works
    GROUP BY Employer
) AS w

嗨，鲍里斯，谢谢你的回答！我将尝试代码。

SELECT w.*,
    (SELECT employee_name FROM works WHERE employer_name = w.Employer AND salary = w.Min AND ROWNUM <= 1) AS EmployeeMin,
    (SELECT employee_name FROM works WHERE employer_name = w.Employer AND salary = w.Max AND ROWNUM <= 1) AS EmployeeMax
FROM (
    SELECT employer_name AS Employer,
        min(salary) AS Min,
        max(salary) AS Max
    FROM works
    GROUP BY Employer
) AS w
