SQL case in order by

Question

I am trying to order by year ascending/descending however I want when the year is 0 to be treated as the newest.

For example:

 2013
 2014
 0

 ORDER BY YEAR DESC should be

 0
 2014
 2013

After some reading I thought this should work but it doesn't:

 ORDER BY CASE WHEN YEAR = 0 THEN 9999, YEAR ASC

Answer 1

Please try:

select  * 
from TableName
order by case YEAR when 0 then 9999 else YEAR end desc
