20761C: Querying Data with Transact-SQL 2016 — Lesson 1: T-SQL Foundations and SELECT Queries

Learning Objectives

• Understand SQL Server objects, schemas, tables, data types, and NULL
• Write SELECT expressions, aliases, filters, and ordering
• Use predicates, ranges, patterns, and logical operators

Detailed Topics

• Understand SQL Server objects: Understand SQL Server objects, schemas, tables, data types, and NULL
• Write SELECT expressions: Write SELECT expressions, aliases, filters, and ordering
• Use predicates: Use predicates, ranges, patterns, and logical operators

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Write and validate a set of foundational business queries.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

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

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply T-SQL Foundations and SELECT Queries in a realistic scenario and validate the result with documented evidence.
