Pipelined function..please help

Question

hi all...
i need a fuction which will split the data n insert into the table...
i created a fuction like this :
CREATE OR REPLACE FUNCTION FN_SPLIT(text      IN VARCHAR2 DEFAULT NULL,delimiter      IN VARCHAR2 DEFAULT ' ')
RETURN SPLIT_TYPE_TABLE PIPELINED
IS
PRAGMA AUTONOMOUS_TRANSACTION;
TYPE ref0 is REF CURSOR;
myCursor ref0;
out_rec SPLIT_TYPE := SPLIT_TYPE(null, null);
--CURSOR MSTFRC IS SELECT * FROM TEMP_SPLIT;
index_      NUMBER(10,0);
BEGIN
     BEGIN
          /*index_ := -1;
          cnt:=0;
          l_str:=text;
          loop
l_n := instr( l_str, delimiter );
exit when (nvl(l_n,0) = 0);
               cnt:=cnt+1;
               INSERT INTO TEMP_SPLIT (ID,NAME)
                         VALUES (cnt,ltrim(rtrim(substr(l_str,1,l_n-1))));
l_str := substr( l_str, l_n+1 );
end loop;*/
          Load_Temp_Splitting(text,delimiter);
          open myCursor for select * from temp_split;
          LOOP FETCH myCursor into out_rec.ID,out_rec.NAME;
               EXIT WHEN myCursor%NOTFOUND;
               PIPE ROW(out_rec);
          END LOOP;
          CLOSE myCursor;
          RETURN;
END;
END FN_SPLIT;
it created succesfully without errors but when i run this function it showing an error like cannot evaluate pipelined function..
my requirement is to split the data like 'as,af,er,yt' split this by comma n insert into the table with row id like
1 as
2 af
3 er
like...
please help friends....
thnks in advance...

function.
And that is one of the most important pieces of the puzzle - the actual error displayed. What is it? (full error, i.e. number + message)
As for the code in the function. That looks a bit like an ugly hack to me. Why the INSERT into table? Why not simply use a local collection or array?
And why a pipelined table function specifically?
The following code demonstrates a string split function:
SQL> create or replace type TStrings as table of varchar2(4000);
2 /
Type created.
SQL>
SQL> create or replace function tokenise( cString varchar2, cSeparator varchar2 DEFAULT ',' ) return TStrings AUTHID CURRENT_USER is
2 strList TStrings;
3 str varchar2(4000);
4 i integer;
5 l integer;
6
7 procedure AddString( cLine varchar2 ) is
8 begin
9 strList.Extend(1);
10 strList( strList.Count ) := cLine;
11 end;
12
13 begin
14 strList := new TStrings();
15
16 str := cString;
17 loop
18 l := LENGTH( str );
19 i := INSTR( str, cSeparator );
20
21 if i = 0 then
22 AddString( str );
23 else
24 AddString( SUBSTR( str, 1, i-1 ) );
25 str := SUBSTR( str, i+1 );
26 end if;
27
28 -- if the separator was on the last char of the line, there is
29 -- a trailing null column which we need to add manually
30 if i = l then
31 AddString( null );
32 end if;
33
34 exit when str is NULL;
35 exit when i = 0;
36 end loop;
37
38 return( strList );
39 end;
40 /
Function created.
