Need a help on this scenario

Question

Hi,
Scenario: monthly data needs to be divided into weekly data acording to the number of weeks in that month.
eg: create table Sdata ( joindate DATE, members number(8));
Insert into Sdata (joindate,members)values ('28-apr-11',8);
Joindate Members
28-apr-11 8
I need the output as weekly wise (equally dividing the members according to the number of weeks in that month). Joindate will be the start date of the week.
Joindate Members
04-apr-11 2
11-apr-11 2
18-apr-11 2
25-apr-11 2
Can someone help me on this.
Thanks
Padma

Post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle you're using.
Do your weeks always begin on Monday? If so
TRUNC (dt, 'IW')will map all dts in the same week to the first point in that week.
For example
SELECT  TRUNC ( DATE '2011-04-28'
              , 'IW'
FROM    dual;produces April 25, 2011 (00:00:00), which is the last Monday on or before the given DATE.
