ERRATA: (groupby not orderby, moreover indentation is messed up)
This should do it
rows=db(db.country.id==db.sales.country).select
(db.sales.product,db.sales.date,db.country.name,db.sales.amount.sum(),
groupby=db.sales.product|db.product.date,db.product.country)
for row in rows:
print row.sales.product, row.sales.date,
row.country.name,row._extra[db.sales.amount.sum()]
BUT 'date' is not a field name in SQL. make it 'date_of_sale' and the
type of that field should be 'date' not string as the default.
