Completed Shipments
Start Timer
0:00:00
Let’s say that you’re a data scientist working on a distribution team at Amazon.
Create a report displaying which shipments were delivered to customers during their membership period.
If the transaction is shipped during the membership period, column is_member should have the value Y. If not, the column should have the value N.
Hint: You may assume that customer_id is unique and that shipments are made only to registered customers.
Example:
Input:
customers table
| Column | Type |
|---|---|
customer_id |
INTEGER |
membership_start_date |
DATETIME |
membership_end_date |
DATETIME |
shipments table
| Column | type |
|---|---|
shipment_id |
INTEGER |
ship_date |
DATETIME |
customer_id |
INTEGER |
quantity |
INTEGER |
Output:
| Column | Type |
|---|---|
shipment_id |
INTEGER |
ship_date |
DATETIME |
customer_id |
INTEGER |
is_member |
TEXT |
quantity |
INTEGER |
