Subject: backfill results for the same month and year
Dear All,
I have the following data
ID CITY QTY MONTH YEAR
-------------------------------
1 Chigago 10 11 2010
1 NewYork 22 11 2010
1 London 54 11 2010
1 Chigago 7 10 2010
1 NewYork 26 10 2010
1 London 33 10 2010
ID = ID PRODUCT.
How can I backfill results with the same ID by month and year, with results like this:
MONTH/YEAR QTY TOTAL
---------------------------
11/2010 86
10/2010 66
and etc.
Please help
Thanks
