Mat,

I'd say it depends on what database you're using. SQL Server does not support this type of syntax, but I don't know about other databases (like maybe Oracle). BTW, for the particular example you gave, you could always do something like this instead:

select sum(jan+feb+mar) as qtr1, 
       sum(apr+may+jun) as qtr2, 
       sum(jan+feb+mar+apr+may+jun) as first6months 
  from myTable
