Oracle Database 19c: PL/SQL Workshop — Lesson 3: Procedures, Functions, Parameters, and Package Design

Technical Scope

• stored procedures and functions
• parameter modes, defaults, and overloads
• package specifications, bodies, and private implementation
• privileges, dependencies, and API contracts

Instructor Demonstration

Demonstrate stored procedures and functions inside an order-processing package with validation, reusable APIs, bulk operations, and database-side diagnostics, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering parameter modes, defaults, and overloads and package specifications, bodies, and private implementation, then test a failure or exception involving privileges, dependencies, and API contracts.

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 Procedures, Functions, Parameters, and Package Design 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 stored procedures and functions, parameter modes, defaults, and overloads, package specifications, bodies, and private implementation, or privileges, dependencies, and API contracts without making an unverified production change.

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