爲什麼在WHERE之後需要ORDER BY薪水？ – Samra 2014-01-29 04:24:30

，因爲薪水將按降序排列，沒有它 – Raja 2016-04-14 17:49:15

像下面這樣的東西應該這樣做。

SELECT Name, Salary 
FROM 
    (
    SELECT Name, Salary 
    FROM   emp 
    ORDER BY Salary desc 
    ) 
WHERE rownum <= 3 
ORDER BY Salary ;

你可以試試。

SELECT * FROM 
    (
     SELECT EMPLOYEE, LAST_NAME, SALARY, 
     RANK() OVER (ORDER BY SALARY DESC) EMPRANK 
     FROM emp 
    ) 
    WHERE emprank <= 3;

這將給予正確的輸出，即使有兩個員工一樣的工資maximun

SELECT a.ename, b.sal 
    FROM emp a, emp b 
    WHERE a.empno = b.empno 
      AND 
      3 > (SELECT count(*) FROM emp b 
        WHERE a.sal = b.sal);

不使用TOP，ROWID，排名等與最古老的SQL還

select empno,salary from emp e 
    where 3 > (Select count(salary) from emp 
     where e.salary < salary) 


Another way : 

    select * from 
    (
    select empno,salary, 
    Rank() over(order by salary desc) as rank from emp) 
    where Rank <= 3; 

Another Way : 

    select * from 
    (
    select empno,salary from emp 
    order by salary desc 
    ) 
    where rownum <= 3;

限制查詢僅顯示前3名最高薪酬員工。：查詢«甲骨文的PL/SQL

create table employee(
     emp_no     integer   primary key 
     ,lastname    varchar2(20) not null 
     ,salary     number(3) 
); 

insert into employee(emp_no,lastname,salary) 
       values(1,'Tomy',2); 

insert into employee(emp_no,lastname,salary) 
       values(2,'Jacky',3); 

insert into employee(emp_no,lastname,salary) 
       values(3,'Joey',4); 

insert into employee(emp_no,lastname,salary) 
       values(4,'Janey',5); 


select lastname, salary 
from (SELECT lastname, salary FROM employee ORDER BY salary DESC)

你可以使用DBMS_STAT_FUNCS.Summary：

SET SERVEROUTPUT ON; 
DECLARE 
    s DBMS_STAT_FUNCS.SummaryType; 
BEGIN 
    DBMS_STAT_FUNCS.SUMMARY('HR', 'EMPLOYEES', 'SALARY',3, s); 
    DBMS_OUTPUT.put_line('Top 3: ' || s.top_5_values(1) || '-' 
         || s.top_5_values(2) || '-' || s.top_5_values(3)); 
END; 
/

輸出：

Top 3: 24000-17000-17000
