Provide a running total for sales of each item in store 5 in January and generate output that is ready to export into a graphing program.

   SELECT Item, SalesDate, CSUM(Revenue,Item,SalesDate) AS CumulativeSales 
   FROM 
   (SELECT Item, SalesDate, SUM(Sales) AS Revenue
   FROM DailySales
   WHERE StoreId=5 AND SalesDate BETWEEN 
   '1/1/1999' AND '1/31/1999'
   GROUP BY Item, SalesDate) AS ItemSales
   ORDER BY SalesDate;
