Question

假设我有一个名为EMPLOYEE的表，其中包含以下属性

(EMPLOYEE_ID, LAST_NAME, FIRST_NAME, MIDDLE_NAME, JOB_ID, MANAGER_ID, Salary)

我能吗？显示第N个最高工资图纸员工详细信息请帮忙

Answer 1

ORDER BY和LIMIT其中10为n + 1：

SELECT
    *
FROM
    employees
ORDER BY
    Salary DESC
LIMIT
    10, 1

（如果你想要第一条记录，请使用LIMIT 0, 1。对于第十条记录，请使用LIMIT 9, 1等。）

Answer 2

try this

put n > 1 to get corresponding results

n = 3必须给你第二个highest salary

 SELECT *   --This is the outer query part 
    FROM Employee Emp1
    WHERE (N-1) = ( /* Subquery starts here */
    SELECT COUNT(DISTINCT(Emp2.Salary))
    FROM Employee Emp2
    WHERE Emp2.Salary > Emp1.Salary)

Answer 3

测试表

CREATE TABLE Test 
(ID INT IDENTITY(1,1),
Salary INT)

INSERT INTO Test
VALUES (100), (200), (300), (400), (500)

SELECT * FROM Test

查询

SELECT TOP 1 Salary
FROM 
    (SELECT TOP 3 Salary FROM Test ORDER BY Salary DESC)q
ORDER BY Salary ASC

在您的子查询SELECT TOP Nth中，其余部分保持不变，它将为您提供所需的结果
