Ratings and reviews

Not always to open. Good application, but please, if possible, add the result of the input query. It is very important to see what comes out when writing this query. This applies to tasks in the "city", for example during execution task the "tasting". So that after selecting the correct answer, a table is displayed, and so that it is displayed as it follows from the request and with the same data. I hope you will hear me. Thanks!

The best FREE app for exploring and learning SQL. Note that this program is completely free with quite a lot of content, except for ads, which can be removed for $5. Honestly, I have prepared to interview with this program)

A good app to get acquainted with SQL. As someone with no background at all, I can say that it gives some understanding of the language. Additionally, the person who thought of the app's name is a genius.
