Honored to speak at #HROUG2025 – celebrating its 30th anniversary in amazing Rovinj! 🎉 Huge thanks to the organizers for keeping this fantastic community going for 30 years! 🙏 Let’s put some old SQL myths to the test together! #Oracle #SQL #Optimizer #Accenture #OracleAce

How do I get the test data these days? My #Accenture colleague @cgohmannde.bsky.social explains. #makeit2025

Who will win? @andreakennel.bsky.social , @danischnider.bsky.social or #ChatGPT? We'll see.

I finish the first day of #MakeIT2025 like I started it: with a session of @andrejsql.bsky.social. This time he talks about parameterized views in Oracle

How can we help the Oracle optimizer to do better with function calls? @danischnider.bsky.social explains. #makeit2025

After the keynote at #MakeITConf, my Accenture colleague @andrejsql.bsky.social shared some interesting insights of table merging. @oracleace.bsky.social

Conferences are always a chance to see my former colleagues of Trivadis again: @andrejsql.bsky.social talking about table merging at #MakeIT2025

MERGE ... RETURNING is now supported in Oracle 23ai. In my view, it deserves more visibility in the documentation — it wasn’t easy to find. Even LLMs still claim it doesn’t exist (some go as far as inventing error codes). Read more: #Oracle23ai #SQL #MERGE #OracleDB blog.sqlora.com/en/merge-and...

Ten years after my first post on the quirks of MERGE and ORA-30926, I took a fresh look at how Oracle 23ai handles it. Clearer error messages, improved diagnostics, and fewer unnecessary restarts. Read the new blog post #Oracle23ai #SQL #MERGE @oracleace.bsky.social blog.sqlora.com/en/ora-30926...

Happy to share my new Oracle Certified AI Vector Search Professional certification! BTW, it is free until May 15 2025 #Oraclecertified #ConvergedDatabase catalog-education.oracle.com/pls/certview...

Did you know that refreshing HCC-compressed materialized views with atomic_refresh=true can multiply storage usage over time? Small details can have massive impacts. Read the new blog post. #Exadata #Oracle #HCC @oracleace.bsky.social blog.sqlora.com/en/when-comp...

The same topic, the same @danischnider.bsky.social, but something has changed, the stage dimension perhaps? Note: stage dimension is not a new term in data warehousing, Dani is speaking about 😃

Excited to speak at #UKOUGDiscover24! Do you also believe that collecting statistics in a data warehouse is not a ‘one size fits all’ approach? And that a targeted approach is part of your role as a data engineer? Join my session on 2 December at 16:00. See you there! ukoug.org/page/UKOUGCo...

@danischnider.bsky.social explains the performance of views on the big stage of the #DOAG2024

Mentioned you, your blog und linked to your package SQM_UTIL, @stewashton.bsky.social. Such package is a must have if you consider using SQL Macros. Thank you.

The wait is over: #DOAG2024 starts tomorrow in Nuremberg. Want to learn about some advanced techniques and concepts around the practical use cases of #SQLMacros in #oracledatabase? Join me in the very first slot at 8:30
