Oracle Database 19c: Advanced PL/SQL — Lesson 2: Dynamic SQL, Metadata-Driven Code, and Safe Extensibility

Technical Scope

• native dynamic SQL and DBMS_SQL
• dynamic DDL and object names
• bind variables, returning, and result description
• injection prevention, validation, privileges, and metadata

Instructor Demonstration

Demonstrate native dynamic SQL and DBMS_SQL inside a slow and privilege-heavy batch subsystem profiled, redesigned, secured, and benchmarked, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering dynamic DDL and object names and bind variables, returning, and result description, then test a failure or exception involving injection prevention, validation, privileges, and metadata.

1. Confirm environment, identity, data, dependencies, and expected result.
2. Complete the product-specific implementation or analysis.
3. Capture commands, configuration, output, logs, transactions, or reports.
4. Explain the operational, security, performance, or business trade-off.

Validation Standard

The Dynamic SQL, Metadata-Driven Code, and Safe Extensibility result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.

• The intended target and ownership are verified.
• The result is supported by reproducible evidence.
• Security, performance, reliability, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance.

Failure Analysis

Diagnose issues in native dynamic SQL and DBMS_SQL, dynamic DDL and object names, bind variables, returning, and result description, or injection prevention, validation, privileges, and metadata without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
