Select all siblings if any child is modified and recalculate qty.

Question

Hi All,
I am in a following situation.
with sales as
    select  1025 CUST_ID, '23239D' ITEM_ID, 1 qty_ord, 1 qty_Ship, 1 qty_Cancel, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS') load_ts, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS') updt_ts  from dual union all
    select   1025, '3434h', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), sysdate + 1  from dual UNION ALL
    select   1025, 'sku324', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS')  from dual union all
    select   1025, 'TRL.33', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS')  from dual union all
    select   1025, 'RTL56', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS')   from dual union all
    select   1025, '34fgh', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS') from dual   union all
    select  1027 CUST_ID, '23239D' ITEM_ID, 1 qty_ord, 1 qty_Ship, 1 qty_Cancel, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS') load_ts, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS') updt_ts  from dual union all
    select   1027, '3434h', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS')  from dual UNION ALL
    select   1027, 'TRL.33', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS')  from dual union all
    select   1027, 'RTL56', 1, 1, 1, TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/08/2013 09:59:25', 'MM/DD/YYYY HH24:MI:SS')   from dual
select * from sales
where updt_ts > sysdate 
Now in the above table if any record is modified then the UPDT_TS will be updated with sysdate.
And every morning an ETL job runs to identify the changes in the above table, While for changes only one record is updated with the Updt_ts. But the requirement is to write a select Query which would select all siblings for any change in the Updt_ts for a given CUSTID. Please let anyone need more information.
The select query returns only 1 record with      ITEM_ID = 3434h, but requirement is it shoud return all siblings associate with cust_id 1025

Hi,
Thanks for posting the sample data; that's very helpful.
Don't forget to post the exact results you want from that data, and explain how you get those results from that data.
See the forum FAQ: https://forums.oracle.com/message/9362002
Define any special terms you use in the explanation, such as "sibling".  How can you tell if 2 given rows are siblings or not?
If being a sibling means having the same cust_id, then maybe:
SELECT  *
FROM    SALES
WHERE   cust_id  IN (
                        SELECT  cust_id
                        FROM    sales
                        WHERE   updt_ts   > SYSDATE
Of course, if updt_ts is always set to SYSDATE when a row is modified, then updt_ts > SYSDATE will never be TRUE in a query run later (unless you're resetting the clock on the database server).
