查询在SQL Server从表中检索上两行

Question

我有一个表叫Employee具有以下字段：

• EMPID
• 工资
• 名称

我想以最高工资获得前两名员工。我如何编写这个查询？

Answer 1

的SQL Server 2000+：

SELECT TOP 2 
     e.* 
    FROM EMPLOYEE e 
ORDER BY e.salary DESC 

MySQL的Postgres的&：

SELECT e.* 
    FROM EMPLOYEE e 
ORDER BY e.salary DESC 
    LIMIT 2 

甲骨文：

SELECT x.* 
    FROM (SELECT e.*, 
       ROWNUM as rn 
      FROM EMPLOYEE e 
     ORDER BY e.salary DESC) x 
WHERE x.rn <= 2 

• Oracle: ROW_NUMBER vs ROWNUM

Answer 2

试试这个..

SELECT * from Employee order by Salary desc limit 2 ; 

Answer 3

SELECT TOP 2 * FROM员工ORDER BY工资DESC;

Answer 4

你应该写这样的东西。

SELECT TOP 2的EmpID，工资，名字从员工ORDER BY工资

Answer 5

又一解决方案：

With NumberedItems As 
    (
    Select EmpId, Salary, Name 
     , Row_Number() Over (Order By Salary Desc) As SalaryRank 
    From Employee 
    ) 
Select EmpId, Salary, Name 
From NumberedItems 
Where SalaryRank <= 2
