Oracle AI Database: Pl/SQL Fundamentals — Lesson 2: Cursors, Records, Collections, Exceptions, and Transaction Control

Learning Objectives

• Assess the components, roles, data, dependencies, and expected outcome for cursors, records, collections, exceptions, and transaction control.
• Operate the required workflow with explicit checkpoints and exception handling.
• Resolve the result through exception logs, transaction outcomes and explain any residual risk.

Detailed Topics

• Cursors
• Records
• Collections
• Exceptions
• Transaction Control
• ownership, prerequisites, data, and acceptance criteria for cursors, records, collections, exceptions, and transaction control
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate cursors, records, collections, exceptions, and transaction control within a PL/SQL solution validating data, processing transactions, handling exceptions, packaging reusable logic, and exposing useful diagnostics. Use representative data and capture exception logs, transaction outcomes so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Oracle AI Database: Pl/SQL Fundamentals activity focused on cursors, records, collections, exceptions, and transaction control. Introduce a realistic case of cursor misuse, isolate the cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Identify who owns the decision, configuration, approval, and production support.
• Estimate how cursor misuse would affect users, data, service, or financial results.
• Define evidence for normal operation, a boundary condition, a failed case, and successful recovery.

Troubleshooting Guidance

When cursors, records, collections, exceptions, and transaction control does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant exception logs, transaction outcomes before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create cursor misuse elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by exception logs, transaction outcomes.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Cursors, Records, Collections, Exceptions, and Transaction Control in a realistic Oracle AI Database: Pl/SQL Fundamentals situation and defend the result with course-specific evidence.
