SQL:如何随机选择并按最高顺序排序

Question

我的架构看起来像这样:

CREATE TABLE users 
    (
     id int auto_increment primary key, 
     name varchar(20), 
     point int(255)
    );

INSERT INTO users
(name, point)
VALUES
('Jack', 1),
('Rick', 5),
('Danny', 11),
('Anthony', 24),
('Barla', 3),
('James', 15),
('Melvin', 12),
('Orthon', 5),
('Kenny', 2),
('Smith', 30),
('Steven', 27),
('Darly', 45),
('Peter', 44),
('Parker', 66),
('Lola', 78),
('Jennifer', 94),
('Smart', 87),
('Jin', 64),
('David', 31),
('Jill', 78),
('Ken', 48),
('Martin', 19),
('Adrian', 20),
('Oliver', 16),
('Ben', 100);

我的sql是:

select id, name, point from users Order by point desc, rand() LIMIT 5

问题是,我的查询没有随机选择5行并按点排序.任何想法,如何解决？这里是sqlfiddle:http://sqlfiddle.com/#!2/18f15/1

Answer 1

select id,name,point from
(select id, name, point from users Order by rand()  
LIMIT 5) abc
order by point desc;
