正在檢索第n個記錄

Question

我有工資表，是否想找到第二大薪水記錄，第三大薪水記錄等等。 要檢索我使用下面的查詢

Select Top 1 * from SalaryTable 
    where salary < (Select Max(Salary) from SalaryTable) 
    order by Salary desc 

同樣第二大紀錄，我怎麼能找到第三大紀錄或第四大記錄等？有沒有辦法檢索特定的記錄？

Answer 1

SELECT TOP 1 salary 
FROM (
SELECT DISTINCT TOP n salary 
FROM employee 
ORDER BY salary DESC) a 
ORDER BY salary 
where n > 1 (n is always greater than one) 

Answer 2

你可以開始使用RANK() function in SQL Server

;WITH CTE AS 
(
SELECT ..., RANK() OVER (ORDER BY emp_salary) AS rn 
FROM myTable 
) 
SELECT ... 
FROM CTE 
WHERE rn = n -- (value of should be replace with numberic number for ex. 1, 2, 3) 

Answer 3

使用RANK（）函數

SELECT * 
    FROM 
     (SELECT * 
       ,RANK() OVER (ORDER BY salary) AS SalRnk 
     FROM SalaryTable) AS tblSal  
WHERE tblSal.SalRnk = 2 -- for second highest record. change this value to 1,2,3,4 etc... for various rank records

Answer 4

你可以把任何值，而不是N，它給你所需的最大薪水。

select top 1 salary 
from(Select Distinct top n salary from Salary order by desc)a 
order by salary Asc
