按低，中，高排序？

Question

所以，我有这个：

select ticket_trackingno, ticket_title, ticket_priority_id, ticket_status_id
from hd_tickets
where ticket_priority_id <> 'None'
and ticket_status_id = 'Assigned'
order by ticket_priority_id desc

有了这个，我的ticket_priority_id列被分类为med，low，high。我想要的是低，中，高。我想知道我该怎么做呢？

Answer 1

ORDER BY CASE ticket_priority_id
         WHEN 'low' THEN 1
         WHEN 'med' THEN 2
         WHEN 'high' THEN 3 END
