As for USB cables, I replaced all of them with a set of decent USB-C cables plus a few sets of “USB-C to *” adapters.

I now have a small box with separate sections for the adapters, plus a zip bag with USB-C cables that takes 20% of the space and fits 80% (and growing) of my use cases.

I’m a developer whose experience with SQL is limited to writing basic queries, window functions and combining those with CTEs.

All my business logic is written in a highly expressive language. It’s conveniently easy to read, change, and test.

And still, I’d like to learn how to implement complex business logic within the realm of my database so I can use it when appropriate.

What resources would you recommend for learning and practicing to write business logic in SQL, including good practices and testing?

In retrospect, a better name for that section could have been "Separate config from code" as it says in one of the first paragraphs.
