Question

我将这些表格包含以下列：

Employee24( EMPLOYEEID, FIRSTNAME, LASTNAME, GENDER, JOBROLES);

Salary25( EMPLOYEEID, SALARYID, JOBROLES, BASICSAL, ALLOWANCES);

显示与职位规模相关的薪资最高和最低的员工的名字和姓氏

SELECT * 
FROM EMPLOYEE24 
WHERE EMPLOYEEID IN (SELECT EMPLOYEEID, JOBROLES FROM SALARY25 GROUP BY JOBROLES));

Answer 1

此查询获取员工ID。我会让你弄清楚如何获得这些名字：

select s.employeeid
from (select s.*, min(basicsal) over (partition by jobrole) as min_bs, 
             max(basicsal) over (partition by jobrole) as max_bs
      from salary25 s
     ) s
where basicsal in (min_bs, max_bs);

Answer 2

您可以使用JOIN表执行Salary25并执行聚合：

select e.firstname, e.lastname, 
       s.HighestSal, s.LowestSal, e.jobroles
from Employee24 e inner join 
     (select employeeid, max(basicsal) as HighestSal, min(basicsal) as LowestSal
      from salary25 
      group by jobrole
     ) s 
     on s.jobrole = e.jobrole;

但是，上述查询根据BASICSAL计算工资，您可能还需要ALLOWANCES。因此，您可以相应地更改公式。
