How to order by column with non-null values first in sql

Question

I need to write a sql statement to select all users ordered by lastname, firstname. This is the part I know how to do :) What I don't know how to do is to order by non-null values first. Right now I get this:

null, null
null, null
p1Last, p1First
p2Last, p2First

etc

I need to get:

p1Last, p1First
p2Last, p2First
null, null
null, null

Any thoughts?

Answer 1

ORDER BY CASE WHEN name IS NULL THEN 1 ELSE 0 END, name;

Answer 2

See Sort Values Ascending But NULLS Last

basically

SELECT *
    FROM @Temp
    ORDER BY CASE WHEN LastName IS NULL THEN 1 ELSE 0 END, LastName
