Technologies or Products Used: Oracle 18c, PL/SQL
Session Summary for Attendees: The most interesting new features Oracle 18c introduces to developers are Polymorphic Table Functions and Qualified Expressions. Polymorphic Table Functions finally allow the developer to define the structure of the returned records at runtime.
Qualified Expressions allow you to define array or record constructors that assign all values in a single statement. What looks at first sight like syntactical sugar is a mighty tool—especially in conjunction with Polymorphic Table Functions.
This talk introduces the concepts of Polymorphic Table Functions and Qualified Expressions and demonstrates real-world use cases and scenarios.
The presentation includes a detailed live demo.
The examples and scripts are available for download.
