Unlock the power of SQL with our intermediate course! Available online, with no enrollment required. Take your SQL skills to the next level and become a SQL expert at your own pace.
This course builds on the SQL Beginner Course. We recommend completing it first if you're new to SQL.
Building on the Beginner Course, this course covers the tools and concepts that separate casual SQL users from professionals. You'll learn to create reusable database logic with views, stored procedures, and triggers. You'll understand how to design efficient schemas through normalization, manage data integrity with transactions, handle errors gracefully, write advanced queries with subqueries and CTEs, and speed up your databases with indexes.
Each chapter includes practical SQL examples across MySQL, PostgreSQL, and SQL Server where syntax differs. By the end, you'll be equipped to build and maintain production-quality databases.
Ready for more? The SQL Advanced Course covers window functions, performance tuning, security, locks, and strategies for working with large databases.
Start with the fundamentals: syntax, data types, DDL/DML commands, JOINs, and functions.
