Local function calling remote function - error

Question

Dear All
i have following remote function wich return some value from both methods ie.
1) select func1(variable, varialbe) from dual@remoteDB; working
2) select func1(variable, varialbe) from dual; -- by making a synonym at local
Now i create a local function funclocal calling remote functino i.e. func1 in this example as:
CREATE OR REPLACE FUNCTION funclocal(locc varchar2, artnoo number)
RETURN NUMBER IS
query_str VARCHAR2(1000);
STKQTYY NUMBER;
artno number(10);
loc varchar2(80);
BEGIN
artno := artnoo;
loc := locc;
query_str := 'select func1(loc, artno) from dual ';
EXECUTE IMMEDIATE query_str
INTO STKQTYY;
RETURN STKQTYY;
END;
compiled successfully.
But when i run as:
SQL> select funclocal('abc', 469183) from dual;
select funclocal('@st3', 469183) from dual
ERROR at line 1:
ORA-00904: "ARTNO": invalid identifier
ORA-06512: at "funclocal", line 11
Please guide me.
Regards

EXECUTE IMMEDIATE query_strAs Andreas states: Why are you using dynamic sql?
From what I see all you need is sth like
create or replace function funclocal (locc varchar2, artnoo number)
   return number
is
begin
   return func1 (locc, artnoo);
end funclocal ;
/even the whole concept of a »local« function seems suspicious. Why do you need that one?
