if you would like to see the non-proprietary standard sql version, it goes 
like this:

   order by 
     case id
       when 3 then 1
       when 7 then 2
       when 2 then 3
       when 1 then 4
                else 0 end

the FIELD function is just shorthand for this CASE expression, which will 
work in all database management systems
