Add a table in this query?

Question

This summarizes the daily values into weekly values from a table.
create table tblBill (
mtrl   varchar2(10),
sales_quantity number,

Thanks for posting the CREATE TABLE and INSERT statements. Remember why you go to all that trouble: it's to let the poeple who wnat to help you re-create the problem and test their ideas. If you post statements that don't work, its not very helpful.
None of your INSERT statements work on my system, because you're trying to insert VARCHAR2S (such as '2012-05-01') into a DATE column. You should insert DATEs into DATE columns. use TO_DATE or DATE literals.
SELECT  Material, qty as Quantity_Sales, fill_year_week as YearWeek
from (
WITH      weeks_vw AS
(SELECT  DISTINCT TO_CHAR(fill_year_day,'IYYYIW') AS fill_year_week
FROM
(SELECT  to_date('2012-05-01','yyyy-mm-dd')  + (ROWNUM-1) AS fill_year_day FROM  DUAL
CONNECT BY      LEVEL <= TRUNC(to_date('2012-05-30','yyyy-mm-dd') - to_date('2012-05-01','yyyy-mm-dd') ) + 1))
SELECT  a.material ,fill_year_week ,SUM(NVL(sales_quantity,0)) AS QTY
FROM
(   SELECT  t.material ,t.sales_quantity, TO_CHAR(t.posting_date,'IYYYIW') AS posting_week
FROM    tblBill t
WHERE   t.material = 'Label1'
AND     t.Posting_date >= to_date('2012-05-01', 'yyyy-mm-dd')
AND     t.Posting_date <= to_date('2012-05-30','yyyy-mm-dd') ) A
PARTITION BY (a.material) RIGHT OUTER JOIN weeks_vw  ON weeks_vw.fill_year_week = A.posting_week
GROUP BY     a.material ,fill_year_week
Order by fill_year_week desc)I don't believe this is the code you're actually running. It references a column called material, but there is no such column in the tbill table.
Now I want to add a second table that looks similar. Today, the answer looks like this:
MATERIALS QUANTITY YEAR_WEEK
Label1       8 086         1219
Again, this indicates you haven't posted your real query. The query above, if it could run, would produce 4 or 5 rows of output, one for each week. Post your actual code, and your actual, complete results.
I want to add one to the column from Table 2 (tblCon) that the answer looks like this:
MATERIAL     SALES_QUANTITY     CON_QUANTITY     YEAR_WEEK
Label1             8 086             1 624             1219How do I proceed?It looks like a job for JOIN. Compute the weekly sum for one table in a separate sub-query, before joining the other table, something like this:
WITH     params          AS
     SELECT     TO_DATE ('2012-05-01', 'yyyy-mm-dd') AS first_posting_date
     ,     TO_DATE ('2012-05-30', 'yyyy-mm-dd') AS last_posting_date
     FROM     dual

     SELECT     TRUNC (first_posting_date, 'IW')
              + (7 * (LEVEL - 1))              AS a_monday
     ,     TRUNC (first_posting_date, 'IW')
              + (7 *  LEVEL)              AS next_monday
     FROM    params
     CONNECT BY     LEVEL <= 1 + ( ( TRUNC (last_posting_date,  'IW')
                                 - TRUNC (first_posting_date, 'IW')
                         / 7
,     tblbill_agg     AS
     SELECT       w.a_monday
     ,       b.material
     ,       SUM (sales_quantity)     AS total_sales_quantity
     FROM          weeks_vw  w
     JOIN       tblbill   b  ON  b.posting_date >= w.a_monday
                        AND b.posting_date <  w.next_monday
