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?
