New SQL Practice Problems

New SQL Practice Problems

I’m trying something new. I get a lot of questions from folks about getting into the Data Engineering space, how to get better, grow, learn, etc.

So I came up with a solution. SQL Practice Problems.

Some moons ago I wrote a Data Engineering Practice repo on GitHub for free, and some 1.2K stars later it was a big hit.

Because that was so popular, I’ve been using my precious weekends to write another one, this time SQL-based. A lot of folks have asked me when I’m going to do a course … and I always say no.

I’m a strong believer that you have to write code to get better and learn!!!

I want to test the appetite for paid practice coding exercises. It was a lot of work but I did it.

These practice problems force learning by using Docker, writing SQL to questions you don’t know about, AND the results are automatically unit-tested for correctness!!!

I like this approach to learning vs just a course where I would talk. Also, having the instant feedback loop of pre-build unit tests to check answers is great as well.

What you can do for me?

I would love for you to give it a try! Give me feedback, what do you like, or not like? Give me other ideas …

I’m thinking about doing one with Polars and Spark maybe. I like the challenge of making people use Docker … and work a little! Please let me know what you think!!
