    How to compare average of last week with previous.

      I have a master calendar with WEEK, DAY, MONTH etc.

      How can I write set analysis expression?

      I guess I need to use for one field smth like max(week) but it may return not the full current week?

       

      Average I'm counting with this expression:

       

      Sum(points)/Count(distinct table_id)

       

      Here we can consider points as smth like sales. And table_id as one closed table in the restaurant,

      Also how can I make this kind of comparison for different restaurants. I have them 3 in database with fields restaurant_id = 1,2,3 respectively.

       

      Thank you for your time!
