SQL and PL/SQL are the languages mastered by every Oracle developer. But the world doesn’t stand still. After the initial training, most developers dive right in and use the acquired knowledge more effortlessly over the years. Best practices are also developed. However, not everyone has the opportunity to explore other aspects of these languages or to familiarize themselves with the new functionalities of recent versions of the Oracle database.

With the release of Oracle 23c, a wealth of new possibilities has been added, both for the ‘standard’ use of SQL and PL/SQL, and for entirely new applications, such as the use and storage of JSON-format data, or even new techniques like Operational Property Graphs or Generative Vector AI.
