Easiest way to eliminate NULLs in SELECT DISTINCT?

Question

I am working on a query that is fairly similar the following:

CREATE TABLE #test (a char(1), b char(1))

INSERT INTO #test(a,b) VALUES 
(\'A\',NULL),
(\'A\',         


        

Answer 1

;WITH CTE
    AS
    (
    SELECT DISTINCT * FROM #test
    )
    SELECT a,b
    FROM CTE        
    ORDER BY CASE WHEN b IS NULL THEN 9999 ELSE b END ;
