I have below query for a single date.
SELECT nsn,thisdate,  
vendor1_code, vendor1_name, qtysum_1, DELIVERED_QTY_1, split_1,
vendor2_code, vendor2_name, qtysum_2, DELIVERED_QTY_2, split_2

                         INNER JOIN dim_date dexp ON pai.dim_date_expiration_id = dexp.dim_date_id

 WHERE rn = 1
 order by thisdate;

Open in new window


But if I need to do the same for a date range on the order date and have to extract the total sum for a vendor group for that order date range.As in the resultset capture.ResultsetThe bottom section for vendor1 and vendor 2(total order qty,total delivered qty leaving the split) is needed.
Thanks for your time

Please let me know.

There is already a date range  in the query

        AND d.thisdate BETWEEN deff.thisdate AND dexp.thisdate

i.e. between a "date_effective" and  a "date_expiration"

What happens if the new query date range isn't compatible with the existing date range?
Could the "split" change during the new date range, and if so how do you want to handle that?

Do you need to alter the where clause to something like this perhaps?
            WHERE ( 
                       d.THISDATE >= to_date('2014-08-12','yyyy-mm-dd') 
                   AND d.THISDATE  < to_date('2014-09-12','yyyy-mm-dd') 
                  )
                  AND to_date('2014-08-12','yyyy-mm-dd') BETWEEN deff.thisdate AND dexp.thisdate

                  AND p.NSN_CODE = '2610-01-214-1344'

Open in new window

Personally I don't think I can offer much detail without some "sample data" (per table) and the "expected result" (based on the sample data).

Please also note I'm not sure why you use a string like '12-AUG-14'  as a date.
I always use to_date() or to_timestamp() depending on the data type in the relevant columns.

I have attached the current resultset,
the query I have run is
SELECT nsn,thisdate,

               LEAD(split) OVER (ORDER BY split)       AS split_2

                GROUP BY p.nsn_code,

 WHERE rn = 1
 order by thisdate;

The export data attached is something Iam expecting .
The query above returns each of those lines for a single date entry
 d.THISDATE ='12-AUG-14 pr '07-AUG-14'.
How to return the same dataset by passing
 d.THISDATE BETWEEN '01-AUG-14' AND '13-AUG-14'  
That way I dont have to run the query each time for a single date,I just have to run it for a date range.
Thanks for your time

I used the with statement and extracted the vendorinfo grandtotals
as below:
with VendorGrandtotal as
