Is this the right way to go about ranking things?

P: n/a
Haven't had much experience with the various OLAP functions in DB2, but
want to work out what the best performing products were yesterday, by
category and by location. Is this the most efficient way to go about

[for this example, transactions is a summary of sales including
location, category, productcode, transdate and (count of) bookings in

select category, location, productcode, bookings
SELECT category,
s.productcode, t.bookings,
dense_rank() over (partition by s.category, s.destination order by
bookings desc) as ranked_bookings
FROM transactions WHERE transdate = current date - 1 days

) as a
WHERE ranked_bookings = 1
