Combining Tables with SQL Exercise


#1

This exercise is under the Multiple Tables Lesson in SQL intermediate. Instruction #2 states:
Don’t remove the previous query.

Add a second query after your first one that only selects rows from the join where description is equal to ‘Fashion Magazine’.

The way I handled this was to simply add :
WHERE description = ‘Fashion Magazine’
to my previous query, which worked fine. For some reason the exercise wants us to create an entirely new query and specify :
WHERE subscriptions.description = ‘Fashion Magazine’;
I don’t understand why we need to do this is the description column is only available in the subscriptions table.

To clarify, my version :
SELECT *
FROM orders
JOIN subscriptions
ON orders.subscription_id = subscriptions.subscription_id
WHERE description = ‘Fashion Magazine’
;

Desired code from exercise:
SELECT *
FROM orders
JOIN subscriptions
ON orders.subscription_id = subscriptions.subscription_id
WHERE subscriptions.description = ‘Fashion Magazine’
;
