Customer Behavior Analysis in SQL

Introduction
Customer cohorts
15. Customer cohort report – exercise
Summary

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: registration_week, country, and registration_count. Order the results by week.

Stuck? Here's a hint!

Use the country column in the customers table. Filter for the appropriate rows:

WHERE registration_date >= '2017-01-01'
  AND registration_date <  '2018-01-01'
