SolveWithSQL

About

SolveWithSQL exists for one simple reason:
most people don’t struggle with SQL because it’s hard — they struggle because it’s taught out of context.

We believe SQL is best learned by solving real problems, one query at a time.

Our Mission

Our mission is to help you think in SQL, not memorize syntax.

Instead of long lectures or abstract examples, SolveWithSQL focuses on:

  • Small, focused challenges
  • Realistic datasets
  • Clear expectations
  • Practical solutions you can reuse at work

Every challenge is designed to answer the question people actually Google:

“How do I write a SQL query that does this?”

How SolveWithSQL Works

SolveWithSQL is built around challenge-based learning.

Each challenge includes:

  • A realistic scenario
  • A clearly defined task
  • Sample tables and data
  • Constraints that reflect real-world usage
  • A clean solution with explanation
  • Common mistakes to avoid

You’re encouraged to try first, fail safely, and then learn from the solution — exactly how SQL is used in practice.

Who This Site Is For

SolveWithSQL is for:

  • Beginners learning SQL for the first time
  • Data analysts who want stronger fundamentals
  • Developers who use SQL occasionally
  • Students preparing for interviews
  • Professionals who want faster, cleaner queries

If you prefer learning by doing, you’re in the right place.

What We Don’t Do

SolveWithSQL is intentionally focused.

We don’t:

  • Teach database administration
  • Dive into vendor-specific quirks too early
  • Overwhelm you with theory
  • Hide solutions behind paywalls

Our goal is clarity, not complexity.

A Growing Learning Path

Challenges are organized by difficulty:

As the library grows, you’ll be able to move from simple SELECT queries all the way to joins, aggregations, performance tuning, and real-world query patterns.

Part of the “SolveWith” Learning Series

SolveWithSQL is part of a growing family of SolveWith… learning sites — all built around the same idea:

Learn faster by solving real problems.

Each site focuses on a single tool or skill, taught through practical challenges instead of abstract lessons.
