[Wayback/Archive] SQLZOO has an extensive set of interactive tutorials spread over these topics:
- basic SQL tutorials gradually getting more difficult (including some Covid-19 materials)
- SQL “how to” style questions
- More involved examples from easy via medium to hard
- A White Christmas challenge
So the above is kind of a continuation of my series of games to learn software and database development PostgreSQL Exercises.
I found it via the first reaction to [Archive] Steve Polito on Twitter: “If you’re like me and want to level up your SQL game, give PostgreSQL Exercises a try. …” / Twitter (which initiated yesterday’s post):
[Archive] Loumarven Payot on Twitter: “@stevepolitodsgn I’ve also tried sqlzoo.net. Almost done with it. Next on my list are dataschool.com and selectstarsql.com” / Twitter
Which means I’ve more sites to try.
These will be the next: [Wayback/Archive] Learn SQL: Interactive SQL Book, from dataschool and [Wayback/Archive] Select Star SQL (which is an interactive book that I should be able to finish in a day full of reading and experimenting).
