Oracle AI Database: SQL Workshop Live Class — Lesson 1: Relational concepts, SELECT statements, projection, filtering, sorting, null handling

Learning Objectives

• Map the roles, prerequisites, data, dependencies, and expected outcome for relational concepts, SELECT statements, projection, filtering, sorting, null handling.
• Build a controlled relational concepts, SELECT statements, projection, filtering, sorting, null handling workflow and record evidence at each decision point.
• Evaluate the result against correctness, security, recovery, performance, and support criteria.

Detailed Topics

• Relational concepts
• SELECT statements
• projection
• filtering
• sorting
• null handling
• Ownership, prerequisites, data, and acceptance criteria for relational concepts, SELECT statements, projection, filtering, sorting, null handling
• Security, control, integration, performance, recovery, compliance, and support implications

Instructor Demonstration

Demonstrate relational concepts, SELECT statements, projection, filtering, sorting, null handling within a learner building reliable Oracle SQL queries and data-change operations that produce correct, explainable, and controlled results. Use representative data and capture query result set and execution record so another practitioner can reproduce and verify the result.

Hands-On Exercise

Complete a controlled activity focused on relational concepts, SELECT statements, projection, filtering, sorting, null handling. Introduce a realistic case of incorrect filtering or null handling, 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

• Establish the current state, desired state, constraints, owners, and acceptable service impact.
• Compare implementation choices for relational concepts, SELECT statements, projection, filtering, sorting, null handling and their rollback consequences.
• Define acceptance evidence based on query result set and execution record, then assign the next improvement owner.

Troubleshooting Guidance

When relational concepts, SELECT statements, projection, filtering, sorting, null handling does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review query result set and execution record before modifying configuration or data. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create a new control, security, performance, compliance, or integration defect.

Validation Checklist

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

Lesson Outcome

Learners can apply Relational concepts, SELECT statements, projection, filtering, sorting, null handling in a realistic Oracle AI Database: SQL Workshop Live Class situation and defend the result with course-specific evidence.
