Why does SoloLearn SQL Lacks code playground?

Question

I think SQL needs hands on practices and a learner must try it...

Answer 1

Part of the reason why Code Playground doesn't have SQL may be attributed to the difference in where you'd normal execute it, in comparison to other languages which can be interpreted/compiled and executed directly. For Code Playground to support SQL, SL will have to figure a way to let users build their own databases before executing queries on those tables. It's not impossible, just not readily available from the start due to some additional points of concern that would have to be sorted out if they were to implement it.
Regardless, our users have found other available sources of practice for SQL in the past. Feel free to use the search bar for a list of SQL practice suggestions.
