SQL: 92 East to Hard Advanced Questions & Projects with Saumyaranjan Panigrahi

Master SQL the way it's actually used in the industry — not just theory.

This is a comprehensive SQL practice pack built from real-world, pharmaceutical-industry data scenarios — the same kind of data structures, queries, and validation challenges I've worked with hands-on in my 4+ years as a Data Analyst.

What's Included:

• 92 SQL questions ranging from Easy → Medium → Hard → Advanced, covering Joins, CTEs, Window Functions, Subqueries, Aggregations, and Data Validation logic
• Practice .sql files with ready-to-run scripts
• Table creation & data insertion scripts — so you're not just answering questions in isolation, you're building and querying real database structures from scratch
• Real-world pharma-based case studies — practice on realistic datasets modeled on clinical trial data, patient records, site performance, and compliance tracking (drawn from my own experience working with CTMS/EDC systems)
• A structured PDF guide explaining the logic and approach behind each solution, not just the final answer

Why This Pack Is Different:

Most SQL practice sets use generic e-commerce or HR datasets. This one is built on pharmaceutical and healthcare-style data — the kind of complex, compliance-heavy data structures used in real analyst roles at companies working with clinical operations, patient data, and regulatory reporting. If you can handle these questions, you can handle SQL rounds at almost any data analyst interview.

Who This Is For:

• Aspiring Data Analysts preparing for SQL interview rounds
• Professionals transitioning into analytics from QA, testing, or other technical backgrounds
• Anyone who wants hands-on, project-style SQL practice instead of just theory

Format:

Instant digital download — PDF + .sql files, self-paced.
