Question

我希望从Employee表获得第二高薪。所以请帮我看看。我通过使用以下查询尝试了它。

Select Max(salary) from Employee;

它从薪水栏中获得最高薪水。但我想要第二高薪。

Answer 1

 select max(sal) from
 (select sal,dense_rank() over (order by sal desc) dr from emp) where dr=2;

如果薪水如5000,3000,3000,2000 ...... Dense_rank（）会给你3000工资的员工

Answer 2

以下是示例

SELECT *
FROM (
    SELECT column1, 
     row_number() over (order by salary desc) as [rownum]
     From sal_table
 ) t
 WHERE [rownum] = 2

如果有多个行具有相同的薪水，您可以使用dense_rank代替row_number()

Answer 3

SELECT MAX(Salary) FROM Employee
WHERE Salary NOT IN (SELECT MAX(Salary) FROM Employee )

这给你第二高。

Answer 4

试试这个

DECLARE @N int
SET @N = 2  -- Change the value here to pick a different salary rank

SELECT Salary
FROM (
    SELECT row_number() OVER (ORDER BY Salary DESC) as SalaryRank, Salary
    FROM Salaries
) as SalaryCTE
WHERE SalaryRank = @N

Answer 5

不仅是第二名工资，而且你可以通过这个查询获得所有你想要的最高工资（比如第3，第5）。

select salary from(select rownum rn,salary from
(select distinct(salary) from emp order by salary desc)) x where x.rn in (1,2,3);

只需替换(1,2,3)代替(3,5)所需的薪水位置，这样就可以获得第3和第5高薪，如：

select salary from(select rownum rn,salary from
(select distinct(salary) from emp order by salary desc)) x where x.rn in (3,5);

Answer 6

还有一个：

 SELECT a.salary
   FROM employee a
  WHERE (:n - 1) = (SELECT COUNT(1)
                     FROM employee b
                    WHERE b.salary > a.salary);

只需将n替换为您想要的第n个。
