Order by ASC 和 DESC 的 MySQL 查询用法

Question

I have this query:

SELECT * FROM project as p inner join users as u on p.user_id = u.user_id
ORDER BY p.projectname, u.date_joined

Now what I want to ORDER by projectname ASC and u.date_joined DESC .

How could I make it this way? I tried this code here but doesn't work:

SELECT * FROM project as p inner join users as u on p.user_id = u.user_id
ORDER BY p.projectname ASC, u.date_joined DESC

Order the projectname ascending works but the descending won't work.

Answer 1

To order project name descending, do this:

SELECT * 
FROM project p 
INNER JOIN users u ON p.user_id = u.user_id
ORDER BY p.projectname DESC, u.date_joined DESC

This will order your result by projectname desc (Z to A) first. For identical projectname records, date_joined will be used for sorting further (latest date first).
