PL/SQL Bulk Loading

Question

Hello,
I have one question regarding bulk loading. I did lot of bulk loading.
But my requirement is to call function which will do some DML operation and give ref key so that i can insert to fact table.
Because i can't use DML function in select statement. (which will give error). otherway is using autonomous transaction. which i tried working but performance is very slow.
How to call this function inside bulk loading process.
Help !!
xx_f is function which is using autonmous transction,
See my sample code
declare
cursor c1 is select a,b,c from xx;
type l_a is table of xx.a%type;
type l_b is table of xx.b%type;
type l_c is table of xx.c%type;
v_a l_a;
v_b l_b;
v_c l_c;
begin
open c1;
loop
fetch c1 bulk collect into v_a,v_b,v_c limit 1000;
exit when c1%notfound;
begin
forall i in 1..v_a.count
insert into xxyy
(a,b,c) values (xx_f(v_a(i),xx_f(v_b(i),xx_f(v_c(i));
commit;
end bulkload;
end loop;
close c1;
end;
I just want to call xx_f function without autonoumous transaction.
but with bulk loading. Please let me if you need more details
Thanks

Can you show the code for xx_f? Does it do DML, or just transformations on the columns?
Depending on what it does, an alternative could be something like:
DECLARE
   CURSOR c1 IS
      SELECT xx_f(a), xx_f(b), xx_f(c) FROM xx;
   TYPE l_a IS TABLE OF whatever xx_f returns;
   TYPE l_b IS TABLE OF whatever xx_f returns;
   TYPE l_c IS TABLE OF whatever xx_f returns;
   v_a l_a;
   v_b l_b;
   v_c l_c;
BEGIN
   OPEN c1;
   LOOP
      FETCH c1 BULK COLLECT INTO v_a, v_b, v_c LIMIT 1000;
      BEGIN
         FORALL i IN 1..v_a.COUNT
            INSERT INTO xxyy (a, b, c)
            VALUES (v_a(i), v_b(i), v_c(i));
      END;
      EXIT WHEN c1%NOTFOUND;
   END LOOP;
   CLOSE c1;
END;John
