Oracle 23ai SQL Features: Q1 2026 Update and What’s Coming

As Q1 2026 closes, let’s take stock of where Oracle 23ai stands and what signals point to the next steps.

Adoption status:

Oracle 23ai has been in production on OCI for nearly two years. On-premises, Enterprise adoption is accelerating — the Oracle community surveys from late 2025 showed roughly 30% of large Oracle shops either already on 23ai or planning a migration within 18 months.

The SQL features with highest reported adoption are, in order: IF [NOT] EXISTS, GROUP BY ALL, the BOOLEAN data type, JSON enhancements, and schema-level privileges. These align with what I’d have predicted — they’re the features with immediate, tangible developer productivity benefits and low migration risk.

AI Vector Search maturity:

The biggest shift in early 2026 is the growing number of production Vector Search deployments. Embedding Oracle AI Vector Search into RAG architectures — using Oracle as the single data store for both relational and vector data — has become a viable, production-tested pattern.

DBMS_VECTOR_CHAIN and the automatic embedding pipeline (generate embeddings without leaving the database) are the features driving this. Oracle processing embeddings natively reduces the architecture to: data in Oracle → embedding in Oracle → vector search in Oracle. No Python preprocessing pipeline required.

What to watch:

Oracle has signaled continued investment in: ONNX model import (run ML models directly inside Oracle), expanded MLE language support (Python stored procedures are being discussed), and deeper APEX integration with AI features for low-code AI application development.

On this blog:

We’ll keep this series going. Weekly Oracle posts, specific and practical. If you have topics you’d like covered — leave a comment or reach out. The Oracle 23ai feature set is rich enough to sustain another full year of deep dives.

Thanks for reading. See you next week.

I’m Attempting to Break a Guinness World Record – Yeah, it’s true!

Some ideas are bigger than the person who has them. This one has been living in my head for a long time, and now it’s real: Guinness World Records has officially accepted my challenge.

From September 4 to 7, 2026, I will teach an uninterrupted class on Introduction to SQL and Database Administration for more than 80 consecutive hours, live, in hybrid format, from a small city in the interior of Rio Grande do Sul, Brazil.

The current world record for the longest computer programming lesson stands at 60 hours. We’re going after 80h.

More Than a Record. A Statement About Education.

The project is called “A Aula Mais Longa” (The Longest Lesson), and the name is exactly what it sounds like. But it’s not about endurance. It’s not a stunt. It’s a declaration.

We live in a country where education is often seen as secondary, something that happens before the “real” career begins, or something reserved for those who already have access. I want to prove something different: that learning can be extraordinary. That students and teachers can be protagonists. That a city in the interior of Brazil can make world history.

The lesson starts on September 4 and ends on September 7: Brazil’s Independence Day. That’s not a coincidence.

What We’re Aiming For

The primary record we’re chasing is the Longest Computer Programming Lesson, officially accepted by Guinness World Records. The current benchmark is 60 hours. Ours will surpass 80.

But we’re not stopping at one title. During the event, we’ll also attempt to set or break records in categories including:

  • Longest Lesson Attended (current reference: 78h 3min)
  • Longest Continuous Student Attendance
  • Most Users to Take an Online Computer Programming Lesson in 24 Hours (current reference: 112,314 participants)
  • Longest Hybrid Technology Lesson
  • Longest Online Lesson
  • Longest University Lesson

The Scale of the Challenge

This won’t be a quiet classroom experiment. The event is designed for real impact, in real numbers:

  • +10,000 simultaneous participants
  • +1,000 professionals trained live
  • +200,000 students impacted online
  • +1 million people reached
  • 4 days of continuous live streaming
  • 800+ bite-sized learning clips generated from the content

The format is hybrid, in-person attendance in Três de Maio, RS, alongside full online participation. There are currently 50 in-person spots and 100 online spots for those who want to be officially part of the Guinness attempt. We’ll evaluate the public interest and review this number if it goes higher.

The Legacy That Stays

The record ends when the lesson ends. The legacy doesn’t.

Every piece of equipment used during the event will be donated to public education initiatives. The 80 hours of content will be edited into short modules and made freely available. Professionals trained during the event become multipliers, people who carry this knowledge forward into their communities and careers.

This is what I mean when I say it’s about education, not just a record. The Guinness certificate is the headline. The real story is what happens after.

What’s Next

We’re currently in the sponsorship and partnership phase (March–April 2026). Public registration is opened!

The final push press coverage, technical rehearsals, and pre-event media  happens in July and August. Then, September 4, we go live. For 80 hours.

The record is just the beginning.
