MYSQL order by text

问题

okay so I know how I can sort by id or number like

$getTicket = $sql->query("SELECT * FROM `ticket` 
                          WHERE `user`='$user->name' 
                          ORDER BY `id` DESC");

I have Status in the ticket table, and in that I have 3 things:

1) Answered 2) Unanswered 3) Done

I want to sort it in this way:

1) Unanswered
2) Answered
3) Done

is there a way to do this?

回答1:

Do simple as-

ORDER BY FIELD(Status, 'Unanswered', 'Answered', 'Done')

回答2:

You can generally use case

SELECT * FROM `ticket` 
WHERE `user` = '$user->name' 
ORDER BY case when Status = 'Unanswered' then 1
              when Status = 'Answered' then 2
              else 3
         end

or MySQL specific find_in_set

SELECT * FROM `ticket` 
WHERE `user` = '$user->name' 
ORDER BY find_in_set(Status, 'Unanswered,Answered,Done')
