Please advise how to display NULL value as a  first record in the query output.

Ex; select distinct (Name) from Table_Name

Output:

Name
====
A
B
C
D
NULL
E
F

I want output like

Name
====
NULL
A
B
C
D
E
F

If you need a particular order, never rely on the "automatic" order of a select. That is, always apply a ORDER BY.
NULL is ordered differently by different DBMS, some sort NULL as highest possible value, others as lowest. To make sure it works as expected, use a combined sort:
  order by isnull(name) desc, name

Aren't you assuming there will be a NULL returned?

i.e. What happens to your logic if it does not get returned?

(looks like you are trying to prepare a drop-down list where the order is important and  a NULL is the "default" or "all")

Sorry for the wrong syntax in http:#a39955357, I was mislead by a prior post.
The first two posts should work fine for MSSQL, and Jim Horn's SQL should be
select distinct (Name) 
from Table_Name 
order by CASE WHEN Name IS NULL THEN 1 ELSE 2 END, Name
