mysql order by, null first, and DESC after

Question

How can I order DESC by a field, but list the NULL values first?

So I\'m having a table:

reuestId | offerId | offerTitle
1        | 1       | Alfa
NU         


        

Answer 1

SELECT *
FROM TableX
ORDER BY (requestId IS NOT NULL)
       , requestId DESC

Answer 2

Try this:

ORDER BY [reuestId] IS NULL DESC, [reuestId] DESC

should work (for mySql)
