SQL for Beginners: First Simple Database & Queries (Free)

Course Introduction

Welcome to SQL for Beginners: Database Development & Queries (Free).

This course is a practical introduction to building and working with databases using T-SQL in SQL Server. Through short, structured workshops and multiple hands-on database projects, you will follow a beginner-first learning path that reinforces core SQL concepts through repetition, practice, and real-world scenarios. It is designed for complete beginners who already have SQL Server installed and ready to use. The course follows a hands-on approach where you type, execute, and observe SQL behaviour directly through guided examples.

While still beginner-focused, this course moves beyond introductory SQL concepts and begins working with real database development tasks. You will create databases and tables, organise database objects using schemas, modify table structures, work with primary keys, insert and update data, and retrieve information using SELECT queries.

The workshops in this course are intentionally beginner-friendly, controlled, and repetitive. The goal is not to overwhelm you with advanced SQL features, but to help you build confidence and familiarity through repeated practical execution.

Throughout the course, you will work with practical T-SQL examples including:

• Creating databases
• Selecting database context with USE
• Creating schemas and tables
• Modifying tables with ALTER TABLE
• Adding primary key constraints
• Inserting, updating, and deleting data
• Writing SELECT queries
• Filtering data using WHERE
• Using COUNT and column aliases
• Exercises and downloadable SQL scripts are also included to reinforce the material and encourage independent practice.

Additional extended practice projects are included through multiple independent business domains, allowing you to apply the same SQL concepts across different database scenarios and strengthen your confidence through repetition and practical problem solving.

What This Course Is

What This Course Is Not

• Not an advanced SQL course
• Not focused on complex query optimisation
• Not covering joins, stored procedures, functions, or transactions
• Not intended for advanced database administration

Outcome

• By the end of this course, you will:
• Have the ability to create databases, schemas, and tables using T-SQL in SQL Server
• Understand how to insert, update, and delete data safely within database tables
• Be able to retrieve and filter data using basic SELECT queries
