How can I get the nulls for the weeks later

Hi all

When I run this code, I get records up to the current week.
How can I view the output that I get nulls for the weeks later. (with the help of the v_numOfWeeks variable in the code)

Thank you
Vikram
DECLARE
   v_query VARCHAR2(4000); 
   TYPE ref_cursor IS REF CURSOR; 
   v_refcur ref_cursor;
   v_sum NUMBER; 
   v_id NUMBER; 
   v_name VARCHAR2(1000); 
   v_weeknum NUMBER; 
   v_pernum NUMBER; 
   v_numOfWeeks NUMBER := 5; 
BEGIN 
v_query := ' SELECT SUM(product_bkg), postn_id, postn_tbl.postn_name, b.week_num, b.period_num
                          FROM ops_cv_extract b, (SELECT row_id, desc_text postn_name
                      FROM s_postn) postn_tbl
                      WHERE lvl_6_id = 5767
                      AND fiscal_year = 2008
                      AND b.week_num < 4
                      AND b.period_num = 3
                      AND b.postn_id = TO_NUMBER(postn_tbl.row_id)
                      GROUP BY postn_id, postn_tbl.postn_name, b.week_num, b.period_num
                      ORDER BY  postn_tbl.postn_name, b.week_num';
                      
OPEN v_refcur FOR v_query;

LOOP 
   FETCH v_refcur INTO v_sum, v_id, v_name, v_weeknum, v_pernum;
   EXIT WHEN v_refcur%notfound; 
   dbms_output.put_line('P'|| v_pernum||'W'|| v_weeknum||' '||v_name||' '||v_sum); 
END LOOP; 
END;

This is the output when I execute this code.

Hello

The subquery dum has 1 to 5 hard coded values:

(
 44                select 1 week_num from dual
 45                union all
 46                select 2 from dual
 47                union all
 48                select 3 from dual
 49                union all
 50                select 4 from dual
 51                union all
 52                select 5 from dual
 53              ) dum ,

Instead, use the following syntax, which produces the values from 1 to n:

(
    SELECT  LEVEL  AS week_num
    FROM    dual
    CONNECT BY  LEVEL <= n
)  dum,

n may be any numeric expression, including a scalar subquery.
