Most SQL courses teach you what to write. Very few teach you how to think. That’s exactly where most learners get stuck. You might already know SELECT, JOINs, and GROUP BY… but when faced with a real problem, things fall apart. Queries feel confusing, logic gets messy, and you’re not sure how to approach the solution. This course is designed to fix that.
In this SQL Portfolio Masterclass, you will learn how to solve real-world case study problems using a clear, structured thinking process. Instead of memorizing syntax, you’ll learn how to break problems down step-by-step using a visual framework: Split – Apply – Combine. This approach helps you understand not just what the query does, but why it works.
Through a complete end-to-end case study, you’ll work with realistic datasets and tackle problems similar to those faced by data analysts in actual business scenarios. Along the way, you’ll master essential SQL concepts like JOINs, GROUP BY, window functions, subqueries, and CTEs applied in context, not in isolation.
