MySQL双排序

Question

我想对我的用户列表进行双重排序。这可能在一个MySQL查询中吗？

1. 按activity
排序
2. 按ID
排序

例如：

1  Jack   Active 
2  Jill   Active 
5  Jens   Active  
3  Harry  Inactive 
4  Larry  Inactive 
6  Luke   Inactive

Answer 1

您可以使用ORDER BY子句根据需要对列进行排序。

SELECT id, name, activity
FROM userList
ORDER BY Activity, ID

我建议阅读MySQL ORDER BY文档。您可以按ASC或DESC顺序对数据进行排序：MySQL: ORDER BY Optimization

Answer 2

SELECT id, name, activity
FROM your_table
ORDER BY activity ASC, id ASC

Answer 3

Select * from table order by activity, ID;

Answer 4

SELECT *
FROM table_name
ORDER BY activity, ID;

Answer 5

是，

SELECT (user.name|| ' ' || user.status) AS sorted_list
FROM STUDENTS
ORDER BY user.status, user.name
