Re: SQL Statement problem

If you don't know the groups ahead of time this will work:

SELECT

       t1.cat_type,
       t1.count_of_type/t3.total as PCT
  FROM
       (SELECT
               t2.cat_type,
               count(*) count_of_type
          FROM 
               workload t2
         GROUP BY
               t2.cat_type) t1,
       (SELECT 
               count(*) total
          FROM 
               workload t4) t3 --Cartesian join intended
