Hi,
How come we use * with clause COUNT to count number of apps at each price point. I thought we need to use COUNT(id ) or COUNT(name)? Don’t we use * to include everything? Thank you

I had a similar questions. I am not understanding why HAVING COUNT(*) > 10… Infact I used HAVING COUNT(price) > 10 and the task was checked off as if done correctly. It was not until I looked at the hint that I realized I had done the query ‘wrong’ (even though the task was ‘completed’ when I used HAVING COUNT(price) > 10)
