Mastering SQL with SQL Server 2022 — Lesson 3: Data Modification and Programmability

Learning Objectives

• Use INSERT, UPDATE, DELETE, MERGE, transactions, and error handling
• Create views, stored procedures, functions, variables, and conditional logic
• Apply permissions, parameterization, and safe data-change practices

Detailed Topics

• Use INSERT: Use INSERT, UPDATE, DELETE, MERGE, transactions, and error handling
• Create views: Create views, stored procedures, functions, variables, and conditional logic
• Apply permissions: Apply permissions, parameterization, and safe data-change practices

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, development, administration, collaboration, analysis, or automation workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Develop a controlled SQL Server data-processing routine.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and preserve evidence of normal, boundary, and failure behavior.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, and operational impact.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, data, permissions, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, ownership, user impact, and business continuity.

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Data Modification and Programmability in a realistic scenario and validate the result with documented evidence.
