Hi.

Would you please give me a workbale sample of the function which can simulate crosstab (pivot).

I need to send two parameters (group_id, type_id) to this function from the view and this function should return the list of comma sepparated values of that type_id.

So if there are three records with type_id values 'a', 'b', 'c' I need to convert them in one text field like 'a, b, c' from the view (query).

Thanks.

Something like this should do it:
create or replace function myCommaList (in_gid in integer, in_tid in integer)
  return varchar2
is
  rsetTab dbms_utility.uncl_Array;
  tablen  binary_integer;
  list    varchar2(4000);
  
begin
  select val bulk collect into rsetTab
  from table1
  where group_id = in_gid
  and type_id = in_tid;
  
  dbms_utility.table_to_comma(rsetTab, tablen, list);
  
  return list;
end myCommaList ;
/
