1,600 PointsIs there a way to access solutions for the 'Review and Practice' challenges in the 'Launch SQL Playgrounds'?
I am having a tough time completing these challenges and I think having access to the solutions will definitely help me learn faster.

231,184 PointsFor just a few of these, the solutions are shown in the video. The rest are just provided as practice exercises.
There is no "answer key", plus there's often more than one possible correct solution.

30,056 PointsI was about to give up, a picture of the final report would be nice.
I could count the 30 books in both locations, and also the 18 unique titles.
It was hard to make the report in the form of two columns, one with title and the next with the count of the title.
What helped to finished it, was to understand the alias needed in the reports we create, after from, create a report(like usual) and don't forget the alias.
Or first create a report and copy/paste it after the from + alias.
