Why sololearn doesn't make Playground for SQL??

Question

Playground for SQL

Answer 1

It would be great to use SQL at the Playground. Sololearn could provide us with one database just for practice.

Answer 2

I think it would be expensive to provide own schema for every user.

Answer 3

The main reason I started the SQL learning was to manipulate a test database... It is a bummer they did not provide one, but the logistics in providing one would be very difficult and practically impossible to make sure it keeps valid data.

Answer 4

Stanford university has a SQL database course that i'm currently trying out it has schema that are downloadable and the answer fields for exercises are really great for finding what your code is actually doing.
