What are some features of ABAP SQL?

The correct choice highlights that ABAP SQL is indeed integrated into the ABAP programming language. This integration allows ABAP developers to seamlessly write SQL statements within their ABAP programs, enabling them to interact with the database to perform operations like select, insert, update, and delete with the same syntax and flow as other ABAP code. The ability to use ABAP SQL directly within ABAP means that developers can leverage database functionalities efficiently while maintaining the data business logic in their applications.

This integration provides a cohesive environment for developers, as they can use ABAP's features (such as data types, structures, and control statements) alongside SQL commands without needing to interface with a separate programming language. This contributes to productivity and maintainability in application development.

While other options may present facts about SQL usage in different contexts, they do not accurately reflect the essential characteristics of ABAP SQL as part of the ABAP development environment. The integration aspect is a fundamental and distinguishing feature critical to the understanding and functionality of ABAP programming.
