Hi all , i want to get out of the data, the most popular good/month i have in my data, i figured out that it would be the one having the maximum sales, so i m using the following formula to see for every month, and every product, and how much were the sales this month, now the solution would be if i can get the max amount and it is therefore the product i need, but how could that be done if i have the following?

select (to_char(salinv_1.inv_date, 'MM'))as "MM",
(to_char(salinv_1.inv_date, 'YY')) as "YY",
(sales_1.prod_code) as "Code",

sum(salpmt_1.amount) as "Total Purchase" from sales_1,salinv_1, salpmt_1
where salinv_1.code = sales_1.inv_code and to_char(salpmt_1.pmt_date,'MM-YY') = to_char(salinv_1.inv_date, 'MMYY')

group by (sales_1.prod_code),

(to_char(salinv_1.inv_date, 'MM')),
(to_char(salinv_1.inv_date, 'YY'))

order by (to_char(salinv_1.inv_date,'YY'))
