MySQL Assignments — Query. Analyze. Master.

Why practice with these assignments?

• Move beyond theory—query real-world–style datasets.
• Build confidence with CRUD, joins, aggregations, and transactions.
• Learn to design schemas, enforce constraints, and write performant queries.
• Get interview-ready with tasks that mirror practical use cases.

How it works

• Choose a topic from the list.
• Attempt questions in order: Basic → Intermediate → Advanced.
• Run queries, verify outputs, and compare alternate approaches.
• Use EXPLAIN/EXPLAIN ANALYZE to understand performance.
• Document your solutions and add the best ones to your portfolio.

Note: For consistency across exercises, assignments reference a database named student. Example emails (when needed) use the domain “@learntoearnlabs.com”.

What you’ll achieve

• Strong SQL fundamentals and problem-solving patterns.
• Clean, normalized schema design with practical constraints.
• Fluency with joins, subqueries, window functions, and CTEs.
