2022 – A bit of a Review
A totally incomplete list of things that I felt were highlights in 2022.

I had the honor and pleasure to do an Interview for the RedStack magazine with Steven Feuertein about his career, databases, PL/SQL, our planet and our responsibility for direct positive action.
This is the whole interview in English.
Wrapping some functionality into a nice little PL/SQL package can make your life so much easier.
I demonstrate this with a small utility-package to deal with Version-Strings.
Having a talk rejected is hard, especially when you really cared about the conference you wanted to speak at. But it doesn’t mean that you are a failure.
I want to explain some reasons why talks might get rejected and why a great abstract doesn’t necessarily mean success.
After the fabulous ATD 2021, I wanted to stay in touch, and one idea was to start an Agile Testing Days Book Club (ATDBC).
The first book we’re reading is “Agile Testing Condensed” by Lisa Crispin and Janet Gregory. Here’s Part 1
SQLcl is a great tool, but it has its problems when it comes to environments other than English/US.
I show a couple of Problems and Strangenesses here and give examples how to work around them.
Ever tried to sort Version-Strings with pure SQL – for example when you want to find the highest Flyway version installed in your database?
Let me show you how you can!
My previous solution to split a string into rows by a delimiter, using pure SQL had a couple of small flaws.
Here is the revisited version that also removes a bit of code duplication.
Steven Feuerstein will do some live refactoring in his “Feuertips” episode #13.
However, in order to confidently refactor, one could use some automated tests that ensure the functionality doesn’t change…
Sometimes we have data that is not split into columns and rows, but SQL can only really thrive on structured data.
But thanks to recursive queries we can split any string into rows – with pure SQL.
