Instruction
Very well done! Let's do one more exercise.
Exercise
Create a report to show the weekly counts of registration cohorts in 2017, based on the customer country. Show the following columns: RegistrationWeek, Country, and RegistrationCount. Order the results by week.
Stuck? Here's a hint!
Use the Country column in the Customers table. Filter for the appropriate rows:
WHERE RegistrationDate >= '20170101' AND RegistrationDate < '20180101'
