Count days in date range?

Question

I have a query like this:

SELECT COUNT(*) AS amount
FROM daily_individual_tracking
WHERE sales = \'YES\'
AND daily_individual_tracking_date BETWEEN \'2010-01         


        

Answer 1

What exactly are you trying to count? The total number of distinct values of daily_individual_tracking_date? Do you need it in the same query as the count(*) query?
