Back home after #POUG2025

Many good discussions, high-quality presentations - and some beers and whiskies 😊

I need some time to sort all these impressions - and I already have an idea for a new session on #POUG2026

With Oracle database 23.9, we can finally use GROUP BY ALL in our SQL queries, as you can read in my latest blog post:

danischnider.wordpress.com/2025/08/05/o...

Oracle 23.9 supports GROUP BY ALL

Aggregating data is now easier than ever before with the newest version of Oracle database 23ai. Oracle version 23.9 supports the GROUP BY ALL syntax.
