Learn sql multiple tables 7 / 10 - cross join

Can anyone please post the solution to this “cross join” section?

Rather than posting the solution, if you post your attempt at solving it you might find that someone will help you understand where your solution is wrong and fix it. :slight_smile:

wjondering where I went wrong

Hi, sorry for the delay in replying to you. :slight_smile:

Taking a quick look at your SQL, it looks like you’re asking for two columns of data to be returned from your query: month, and COUNT(*) AS subscribers.

If we re-write your SELECT as a single line:

SELECT month COUNT(*) AS subscribers

can you see what is missing? :slight_smile:
