Trying to get the left join challenge but the editor shows me the error: Did you remember to add the WHERE clause?
This is my code:
SELECT *
FROM newspaper
LEFT JOIN online
ON newspaper.id = online.id
WHERE online.id IS NULL;
What can be wrong?
Finally clicked the “get solution” button and found out that the code is correct. So i guess the checker is failing if you removed the query from step 1.
The error message should be a “Do not remove first query” or “Keep the query from step 1” but no “Did you remember to add the WHERE clause?”
