Question

任务是“编写一个SQL查询以按职务分类计算员工的最高工资。（输出显示别名）。

创建了两个表，Employee和Job_Title。 Employee表由Salary组成，而Job_Title表由作业分类组成，例如'Manager'。

我所显示的当前代码，该分类中具有最高工资的员工，但Alias未显示。它只显示该员工的所有信息。

这是我的代码：

SELECT  *
FROM    Employee
WHERE   Salary IN (
        SELECT  MAX(Salary) AS 'Maximum_Salary_Class'
        FROM    Employee
        WHERE   JobID IN ( SELECT   JobID
                           FROM     Job_Title_Table_
                           WHERE    Job_Classification = 'Manager' ) );

Answer 1

试试这个。

;with cte as
(
select E.*,J.Job_Classification,Dense_RAnk() over(partition by J.Job_Classification order by E.Salary) as DenseRank
from Employee E
inner join Job_Title J on E.JobID = J.JobID
)
select * from cte
where DenseRank = 1

我试图了解你的目的。如果我没弄错，请告诉我。

Answer 2

这样的事情：

select t.Job_Classification, max(e.salary) as 'Maximum_Salary_Class' 
from Employee e join Job_Title_Table_ t on e.JobID = t.JobId
group by t.Job_Classification;

Answer 3

我想你想得到这个

SELECT E.*,Job_Classification 
FROM Employee
,(
  SELECT J.JobID,J.Job_Classification,MAX(Salary) AS 'Maximum_Salary_Class'
  FROM Employee AS E
  ,Job_Title_Table_ AS J
  WHERE E.JobID = J.JobID
  AND Job_Classification = 'Manager'
  GROUP BY J.JobID,J.Job_Classification
) AS EJ
WHERE E.JobID = EJ.JobID
AND Salary = Maximum_Salary_Class
