SQL Server and T-SQL Development: From Basics to Advanced Queries

Databases power almost every modern application and data analysis workflow. Understanding how to interact with them using SQL Server and T-SQL is a foundational skill for developers, analysts, and database administrators alike. This text-based course guides you from absolute database basics to writing complex, optimized queries. You will learn how to structure databases, manipulate data, and implement advanced logic to solve real-world data challenges on Windows, macOS, or Linux. What you'll learn: - Understand core relational database concepts, schemas, and T-SQL syntax from the ground up. - Write queries to filter, sort, aggregate, and join data from multiple tables. - Apply built-in functions, CASE statements, and type casting to transform raw data. - Implement advanced querying techniques using Common Table Expressions (CTEs) and window functions. - Optimize query performance using indexes, execution plans, and temporary tables. - Create reusable database logic using stored procedures and dynamic filtering. The course begins with essential database definitions and setup instructions for your preferred operating system. You will then progress through structured written explanations and practical code examples, moving from basic data manipulation to advanced optimization techniques. Designed entirely for beginners, this course requires no prior programming or database experience.
