Answer Happy

Looking for help on 19
18 Create a view named category_region
-- over the category, region, store,
salestranaction, includes,
-- and product tables that summarizes total
quantity sold by region and category. The view
-- should have columns:
-- categoryid, categoryname, regionid,
regionname, totalsales
CREATE VIEW category_region AS
SELECT c.categoryid, c.categoryname, r.regionid, r.regionname,
i.quantity AS totalsales
FROM region r
INNER JOIN store s ON r.regionid = s.regionid
INNER JOIN salestransaction t ON s.storeid = t.storeid
INNER JOIN includes i ON t.tid = i.tid
INNER JOIN product p ON i.productid = p.productid
INNER JOIN category c ON p.categoryid = c.categoryid;
Question 19 Using the view created in 18, which region
has the most sales for
-- each category.
-- you should get the result
-- categoryname regionname totalsales
-- Electronics Chicagoland 6
-- Climbing Indiana 17
-- Camping Tristate 9
-- Footwear Tristate 20
-- Cycling Chicagoland 13
This is what I have so far but it is not giving me the desired
output
select categoryname, regionname, max(totalsales) as
totalsales
from category_region
group by categoryname, regionid
order by categoryname;
