Calling SQL Stored procedure from PLSQL function

Question

Hi,
I have created a simple function to return a value that is pulled back from SQL server.
FUNCTION
FUNCTION CALC_PASS_FAIL
i_lidded_sn IN TMP_CHIP_ATTR.LIDDED_SN%TYPE
RETURN NUMBER
IS
tmp_result NUMBER;
BEGIN
[email protected](i_lidded_sn,'OadmBarActive',tmp_result);
RETURN tmp_result;
END CALC_PASS_FAIL;
OUTPUT
--When executed as a procedure, i get the required output:
DECLARE
x INT;
BEGIN
x:=EQDAS_MISC.CALC_PASS_FAIL('OADM004548');
dbms_output.put_line(x);
END;
0 <------ expected output
PL/SQL procedure successfully completed.
When executed as a simple function call, i don't get any output:
SELECT CALC_PASS_FAIL ('OADM004505') FROM dual;
Any input will be greately appretiated.
Thanks,
Shashi
PS: I am using the DB Link setup usign DG4MSQL

just wondering it works as procedure as the function misses double quotes:
dbo.GetChipPareto
should be
"dbo"."GetChipPareto"

Tested a small example using a function like:
create or replace function test(
v_ut1 in varchar2)
RETURN varchar2
IS
v_ut2 varchar2(255);
BEGIN
"dbo".OTG_TEST3@dg4msql( v_ut1, v_ut2);
RETURN v_ut2;
END test;
The function calls a SQL Server procedure OTG_TEST3 just returning the passed string and it guarantees data integrity.
Result using a stored procedure:
SQL> DECLARE
2 ret integer;
3 v_ut1 varchar2(255);
4 v_ut2 varchar2(255);
5 BEGIN
6 v_ut1 :='Hello World';
7 v_ut2 :='';
8 "dbo".OTG_TEST3@dg4msql( v_ut1, v_ut2);
9 dbms_output.put_line('Input value: ' ||v_ut1||' - Output value: '
||v_ut2);
10 END;
11
12 /
Input value: Hello World - Output value: Hello World
And calling now the function:
select test('Hello') from dual;
returns Hello
