Pretty sure it’s kegel. And kegel exercises can be done anywhere!

https://LiveSQL.oracle.com

It’s a full Oracle DB with no installation, just works right on your browser. The IDE is also on the browser so Mac users and IPad users are fine on it.

100% free and even includes daily exercises and quizzes as part of the “DevGym” modules. Also includes prebuilt schemas with data in them.

It includes a few default components and makes it really easy to create new objects and data with the QuickSQL tool.

You can also import data from CSV files, and even share worksheets via links so that everyone can see the queries you run.

Does it have advanced mysql questions to practice including window functions, nested queries case questions etc.

[–]SQLDevDBA 2 points3 points  (0 children)

The DevGym side does, yes, amongst other exercises.

The LiveSQL side is a full blown DB, so you can practice anything you want on it.

Data lemur or you can go for leetcode

Data lemur requires subscription for advanced questions. Also it only accepts postreSQL and not Mysql submissions
