In this episode, hosts Lois Houston and Nikita Abraham discuss new features in Oracle Database 23ai related to Data Manipulation Language (DML). They are joined by Senior Principal Database & MySQL Instructor, Bill Millar, who explains the concept of unrestricted parallel DMLs and their importance in speeding up large operations and maintaining summary tables. The discussion then turns to unrestricted direct loads, examining the evolution of direct loads with 23ai and the broader impact of these changes.

Nikita: Welcome to the Oracle University Podcast! I'm Nikita Abraham, Principal Technical Editor with Oracle University, and with me is Lois Houston, Director of Innovation Programs.

Lois: Hi there! In our last episode, we discussed a ground-breaking caching solution in Oracle Database 23ai, known as True Cache. We spoke about its configuration and deployment, and explored how to apply True Cache to our applications.

Nikita: Today, we're going to talk about two Oracle Database 23ai new features related to Data Manipulation Language, or DML. The first is Unrestricted Parallel DMLs and then we'll move on to Unrestricted Direct Loads. We'll talk about the situation prior to 23ai, identify the improvements that have been made, and look at their benefits.

Lois: And returning for another episode is Bill Millar, our Senior Principal Database & MySQL Instructor with Oracle University. Hi Bill! So, to start, can you explain what unrestricted parallel DMLs are and why they are important, especially in the context of Oracle Database?

Bill: The Oracle Database allows DML statements such as inserts, updates, deletes, merge to be executed in parallel by breaking those statements into smaller task. These transactions can contain multiple DML statements. And they can modify multiple different tables.
