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
