PostgreSQL Exercises

Posted by jpluimers on 2023/01/11

[Wayback/Archive] PostgreSQL Exercises

This site was born when I noticed that there’s a load of material out there to help people learn about SQL, but not a great deal to make it easy to learn by doing. PGExercises provides a series of questions and explanations built on a single, simple dataset.

It was funny, as I bummped into right after writing the article Enabling GitHub pages to a HTML or markdown GitHub project is dead easy: Delphi deadlockempire is now hosted on (which reached the top of the blog queue yesterday).

After reading the [Wayback/Archive] PostgreSQL Exercises: Getting Started, start the exercises at [Wayback/Archive] PostgreSQL exercises: basic exercises.

There is no login needed, which I really like.

Note that some of the assignments are hard, and can have multiple results, see for instance [Archive] Fahru on Twitter: “this: … I FINALLY completed it, and any win is worth tellingšŸ„³ took me like one hour on and off. The “more than 30$” requirement is bizarre šŸ˜‚ a bit different than the official answer so I’m digging up more about this learned a heck ton, worth the time! ” / Twitter
