Answer 1

ORDER BY 
    CASE 
    WHEN Name IS NULL THEN 1 
    WHEN Name = ''    THEN 2 
    ELSE 3 
    END DESC, 
    Name ASC

You can do it like this:

ORDER BY CASE WHEN Name IS NULL then 3 WHEN Name = '' THEN 2 ELSE 1 END, Name

It will order with by the number in the case first and afterwords by the Name.

Answer 3

ORDER BY (CASE WHEN Name IS NULL THEN 1 WHEN Name IS NULL THEN 2 ELSE 3 END) DESC

Answer 4

ORDER BY 
CASE 
    WHEN Name IS NULL THEN 1 
    WHEN Name = '' THEN 2 
    ELSE 3
END DESC,
Name ASC
