Thanks to everyone for all comments here. I made https://interactivesql.com https://interactivesql.com to help all those people who just start to learn databases, SQL, queries, and more. I am compiling 120+ lessons now to cover everything from the basics (select, join, group by, to CTEs, Analytic Functions, performance, reporting, and more) Hope this helps. Feel free to let me know what do you think about it.
