2. Question 1

Instruction

Question 1 is all about customer acquisition.

Exercise

Create a report that compares the number of acquired customers in weekly registration cohorts across selected channels. Remember, this is during the first quarter of 2017. Show the following columns:

• RegistrationWeek
• DirectCount (the number of customers from the 'Direct' channel in the given cohort).
• SocialCount (the number of customers from the 'Social' channel in the given cohort).
• ReferralCount (the number of customers from the 'Referral' channel in the given cohort).

Order the results by week.

Stuck? Here's a hint!

Join the Customers and Channels tables to get the channel names.

Use the COUNT(CASE WHEN ...) construction to count the customers from each channel.

Use the DATEPART() function to extract the week of registration.
