There was one interactive resource on SQL. Don't you remember?

Question

Books

There was one interactive resource, a game site. There was a story about learning SQL. Black screen, something like a retro console, green text. If I'm not mistaken, then the screen emitted a convex screen, but I don't remember exactly. At the very beginning, it was necessary to display SELECT data about residents, then the tasks became more complicated

Answer 1

Perhaps a series (of 7 books) "All Higher Mathematics" will do.
Here you can see if the presentation style suits you or not.

Answer 2

In October last year, there was a good answer on this topic: How can an adult develop in mathematics?

Answer 3

Here with the "black console" I remember only one, datamonkey.pro. But I don't remember what the assignments were. And so, a classic and very cool resource is sql-ex.ru , but this is clearly "not right".
