Key Features of Oracle SQL in Oracle Database 19c

Oracle Database 19c represents a significant milestone in the journey of Oracle databases, focusing on enhancing performance, scalability, and automation.

SQL, as the heart of database interaction, has numerous features in Oracle Database 19c designed to optimize your database processes. Let's dive into the key features of Oracle SQL in Oracle Database 19c.

1. Improved JSON Support

JSON has become a crucial component for data interchange, and Oracle Database 19c introduces improved support for JSON. The enhancements include faster performance, increased storage efficiency, and the ability to edit and search JSON data effectively. This is pivotal for applications that rely extensively on JSON data.

2. Automated Indexing

Oracle Database 19c automates the index creation process using machine learning algorithms. This feature ensures optimal performance by automatically identifying and implementing the best indexing strategies for your queries. It continuously evaluates the workload and adjusts as necessary, reducing the manual effort involved in tuning performance.

3. Enhanced SQL Performance Tuning

SQL performance tuning has been streamlined with Oracle SQL in 19c. The inclusion of automatic SQL plan management and adaptive query optimization ensures that your queries run efficiently. For insights on optimizing your SQL queries, check out this guide on Oracle SQL Optimization.

4. In-Memory Enhancements

Oracle Database 19c continues Oracle's commitment to in-memory processing, delivering improved analytical performance. The dual-format architecture allows faster analytic queries by keeping data in memory in both row and columnar formats. Moreover, 19c introduces "Automatic In-Memory Management," which monitors workload patterns and optimally places data in memory.

5. SQL Quarantine

A novel feature in Oracle Database 19c is SQL quarantine. When a SQL statement degrades system performance, SQL quarantine helps by preventing repetitive execution of the problematic SQL. This ensures that the problematic SQL does not affect the overall system stability.

6. Enhanced Date and Time Handling

Date and time data types witness further improvements in Oracle Database 19c. Leveraging SQL's ability to manage date and time efficiently can significantly enhance your data manipulation operations. Learn how to manipulate dates effectively with Oracle SQL Date Manipulation.

7. Advanced PL/SQL Features

Oracle Database 19c extends the capabilities of PL/SQL with features like polymorphic table functions and enhanced triggers. These features provide flexibility and greater control over data processing and business logic, making PL/SQL development more powerful and efficient.

8. SQL Macros

Introduced in Oracle Database 19c, SQL Macros allow users to encapsulate complex SQL logic inside functions that can be reused across applications. This not only improves code maintenance but also boosts performance by enabling seamless query optimization.

9. Integration with Oracle Analytics Cloud

Oracle SQL in Database 19c seamlessly integrates with Oracle Analytics Cloud, facilitating business intelligence applications. This integration allows real-time analytics and ad-hoc reporting, empowering users to derive meaningful insights from their data.

Conclusion

Oracle SQL in Oracle Database 19c is packed with features that aim to enhance performance, automate routine tasks, and provide advanced data management tools.
