Udemy – SQL for Data Analysts: 160 Hands-On Coding Exercises

Want to actually get good at SQL — not just watch tutorials, but write real queries and get instant feedback? This course gives you 160 hands-on SQL coding exercises built specifically for aspiring and working data analysts.

Unlike video-only SQL courses, this is a practice-first course. You’ll write actual SQL queries directly in Udemy’s built-in coding environment, run them against real datasets, and get immediate pass/fail feedback — just like a real data analyst job or a technical SQL interview.

The course is structured in three progressive tiers:

• Beginner (50 exercises): SELECT, WHERE, ORDER BY, GROUP BY, basic JOINs, and aggregate functions
• Intermediate (50 exercises): Multi-table JOINs, subqueries, CASE statements, window functions, and date/string manipulation
• Advanced (50 exercises): CTEs, complex window functions, query optimization, nested subqueries, and analyst-style business problems
• Mini Projects (2 projects): Real-world business scenarios using CTEs, window functions, multi-table joins, cohort analysis, RFM segmentation, and analyst-style insights on e-commerce and streaming data.
