T-SQL Querying Fundamentals: Write Transact-SQL from Scratch

To work effectively with databases in SQL Server, you need to speak their language. Transact-SQL (T-SQL) is the powerful dialect that unlocks the ability to retrieve, manipulate, and analyze relational data. This text-based course guides you from absolute beginner to writing confident, efficient queries. You will learn how to extract precise datasets, join tables, and use built-in functions to solve real-world data problems. What you'll learn: - Understand core relational database concepts and foundational T-SQL syntax. - Retrieve and filter data using SELECT statements, WHERE clauses, and sorting techniques. - Combine data from multiple tables using INNER, OUTER, and CROSS JOINs. - Group and aggregate data to perform basic business calculations and reporting. - Apply built-in T-SQL functions for string manipulation, date arithmetic, and modern JSON parsing. - Write subqueries and simple Common Table Expressions (CTEs) to organize complex query logic. You will start with the fundamental terminology of databases and basic query structures. As you progress through the written explanations and practical code examples, you will explore advanced filtering, multi-table joins, and modern querying techniques. Designed for absolute beginners, data analysts, and aspiring developers, this course requires no prior SQL or programming experience.
