In VFP you coudl order by like this:
select firstName+lastName as fullName,firstName,lastName from myTable order by fullName
or:
select firstName+lastName as fullName,firstName,lastName from myTable order by 1
but not like this:
select firstName,lastName from employees order by firstName+lastName
when you don't need that calculated column in result (just using in ordering).

In SQL server however all of these are valid:
select firstName+lastName as fullName,firstName,lastName from myTable order by fullName
select firstName+lastName as fullName,firstName,lastName from myTable order by 1
select firstName,lastName from myTable order by firstName+lastName
In the same manner you could do:
select newId(),* from mytable order by 1
or:
select * from mytable order by newID()
