Using variable in physical table of type "select"

Question

Hello!
I have to use query as physical table (in Administration tool - http://file.qip.ru/file/120930377/8713693/1_online.html):
SELECT ID, CODE
FROM TABLE (pkg.output('1','2')) This code works well. I need to insert instead of parameters '1' and '2' session variables, which will be set from Dashboard.
How to put variable in this query? Variants like @{test} don't work.

Hi
I have a working example:
select * from table(get_emps('VALUEOF(NQ_SESSION.USER)'))
where
CREATE OR REPLACE FUNCTION GET_EMPS(P_USER VARCHAR2:='SUPPLIER2')
RETURN EMP_TYPE_LIST
IS
EMPS EMP_TYPE_LIST:=EMP_TYPE_LIST();
R EMP_TYPE:=EMP_TYPE(NULL,NULL,NULL,NULL,NULL);
i pls_integer:=0;
CURSOR C_EMP(C_USER EMPLOYEES.USER_ID%TYPE) IS
SELECT EMPLOYEE_ID,FIRST_NAME,LAST_NAME,SALARY ,USER_ID
FROM EMPLOYEES WHERE upper(USER_ID)=upper(C_USER);
BEGIN
OPEN C_EMP(P_USER);
LOOP
FETCH C_EMP INTO R.EMPLOYEE_ID,R.FIRST_NAME,R.LAST_NAME,R.SALARY,R.USER_ID;
EXIT WHEN C_EMP%NOTFOUND;
i:=i+1; emps.extend; EMPS(i):=R;
END LOOP;
RETURN EMPS;
END;
and
CREATE OR REPLACE TYPE EMP_TYPE AS OBJECT
EMPLOYEE_ID NUMBER(6),
FIRST_NAME VARCHAR2(20),
LAST_NAME VARCHAR2(25),
SALARY NUMBER(8,2),
USER_ID VARCHAR2(30));
and
CREATE OR REPLACE TYPE EMP_TYPE_LIST AS TABLE OF EMP_TYPE;
My employees table contains an extra column, called user_id, which has different values: 'Administrator','SUPPLIER2' and so on
Best regards
