需要帮助SQL Server查询。

I want write this query in SQL Server

我想在SQL Server中编写这个查询

from (
    select DISTINCT salary 
    from employee 
    order by salary desc
) 
where rownum = 3;

2 个解决方案

#1

See ROW_NUMBER():

看到ROW_NUMBER():

E.g.,

例如,

WITH EmployeeSalary AS
(
    select salary, 
        ROW_NUMBER() OVER (order by salary desc) AS 'RowNumber'
    FROM employee 
    group by salary --you can't use DISTINCT because ROW_NUMBER() makes each row distinct
) 
SELECT * 
FROM EmployeeSalary 
WHERE RowNumber = 3;

#2

SELECT DISTINCT salary 
FROM employee 
WHERE rownum = 3 
ORDER BY salary

The caps are optional. Is rownum a column in employee or are you looking for only the third row returned?

帽子是可选的。rownum是employee中的一列，还是只返回第三行?
