I have done this before using this approach (this has not been syntax checked):

     select last
           ,first
           ,max(first_code) || max(second_code) || max(third_code) ||
     ...etc., etc. until the max.
     from
     (select last
            ,first
            ,case when csum(1, code asc) = 1 then code else '' end         as
     first_code
            ,case when csum(1, code asc) = 2 then ',' || code else '' end  as
     second_code
            ,case when csum(1, code asc) = 3 then ',' || code else '' end  as
     third_code
            ,  ...etc., etc. until the max number ...
        from tab1
        group by 1,2) DT1
     group by 1,2;

This method assumes that you do have a maximum number of codes. If that is not the case, this will not work.

Hope this helps.

Thanks,

Barry
