The Evolution of SQL in Oracle 19c: Automation and Efficiency
The release of Oracle Database 19c marked a significant shift toward the "Autonomous Database" vision, where the database software takes over labor-intensive manual tuning tasks. For SQL developers and DBAs, this version introduced features that not only simplify code but also ensure that performance remains consistent even as data grows. 1. Intelligent Performance Tuning
One of the most discussed features in 19c is Automatic Indexing. Historically, creating and maintaining indexes was a manual process of trial and error. Oracle 19c uses machine learning to monitor the application workload, identify missing indexes, and validate them before they are fully implemented. This is complemented by Real-Time Statistics, which allows the optimizer to gather essential data during DML operations rather than waiting for scheduled maintenance windows, leading to more accurate execution plans for SQL queries. 2. Enhanced SQL and PL/SQL Capabilities
Developers gained several new tools to write cleaner, more efficient code:
SQL Macros: These allow developers to encapsulate complex SQL logic into a macro that is expanded at compile-time, improving both code reusability and performance compared to traditional PL/SQL functions.
SQL Quarantine: To prevent "runaway queries" from exhausting system resources, Oracle 19c can automatically "quarantine" SQL statements that exceed defined execution thresholds, ensuring they do not impact other users.
Polymorphic Table Functions (PTF): These functions can accept any table as input and produce a table with a dynamic set of columns, providing a powerful way to implement custom logic that fits into a standard SQL query. 3. Hybrid and Modern Data Structures
The introduction of Hybrid Partitioned Tables in 19c allows a single table to have some partitions stored locally in the database and others stored in external files (like CSVs or Parquet on cloud storage). This provides a seamless way to query "hot" transactional data and "cold" archival data using standard SQL. Additionally, 19c significantly enhanced JSON support, allowing developers to treat JSON documents with the same rigor as relational data, including easier syntax for updates and better performance for JSON stored in LOBs.

Oracle Database 19c is the final, most stable version of the 12.2 release family, offering premier support through at least 2026 and extended support through 2029. Unlike its predecessor, 18c, which had a shorter support lifecycle, 19c is positioned as the “innovation release” for production environments. For SQL practitioners, this means that the features introduced in 19c are robust, well-tested, and intended for long-term deployment. Consequently, organizations migrating to or adopting 19c gain access to a mature SQL engine that balances innovation with stability. JSON data type : Support for JSON data
Oracle Database 19c is the long-term support release (also known as the "terminal release" for the Oracle Database 12.2 and 18c/19c family). It is widely considered the most stable, feature-rich version for enterprises, with premier support lasting until at least 2027 (and extended support beyond).

Oracle Database 19c, the final long-term support release of the 12c family, introduces several key SQL and developer-centric enhancements designed to simplify coding and improve performance. Top SQL & Developer Features
SQL Macros (SQM): Starting from version 19.7, developers can use SQL table macros to factor out complex logic into reusable, parameterized constructs that act like polymorphic views.
LISTAGG DISTINCT: The LISTAGG function now supports the DISTINCT keyword, making it easier to aggregate unique strings without complex subqueries.
Hybrid Partitioned Tables: This feature allows a single table to contain both internal partitions (stored in the database) and external partitions (stored in files or cloud storage), optimizing storage costs for large datasets.
JSON Enhancements: New features include JSON_MERGEPATCH for partial updates, JSON_SERIALIZE for data formatting, and GeoJSON support. Performance & Automation New Features in Oracle Database 19c | PDF - Scribd
Oracle Database 19c is a long-term support release that introduces several advanced SQL and PL/SQL features designed to automate performance tuning, enhance data management, and simplify application development. Core SQL and Development Enhancements
Automatic Indexing: This landmark feature uses machine learning to automatically create, test, and manage indexes. It identifies candidate indexes, validates them against performance gains, and keeps only those that improve query speed without impacting existing workloads.
Hybrid Partitioned Tables: You can now create tables where some partitions are stored internally in the database while others reside in external files (like CSVs on cloud storage). This is ideal for archiving "cold" data while keeping "hot" data readily accessible in the same table structure.
JSON Improvements: Oracle 19c significantly expands JSON capabilities with new functions like JSON_MERGEPATCH, enhancements to JSON_OBJECT, and the ability to map JSON data directly to SQL object types.
Real-Time Statistics: To prevent performance drops due to stale data, the database now gathers essential statistics dynamically during conventional DML (Data Manipulation Language) operations.
LISTAGG DISTINCT: Developers can now use the DISTINCT keyword within the LISTAGG function to remove duplicate values from a concatenated string, a common request in previous versions. Key PDF Documentation for Oracle 19c
