Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Amazing to see different people using exactly the solution like yours =)
Nice kata!
However, I think it would be nice to specify that the very first line of the code has to be modified as well, as it's incorrect.
Pretty easy kata! Thanks!
Pretty good kata! Really liked it.
I think this kata is nice. However, some additional tests are required.
For example if I use the following code:
SELECT name, author, copies_sold FROM books WHERE copies_sold > 2000;
It actually passes all the 7 tests as for January 2024. Just adding a test with a couple of lower numbers than 2000 (let's say we have a less successful bookstore and the maximum amount of books sold per author will be let's say 100.) In this case the code above won't work.
