## What is SQL Query Logic?

SQL Query Logic is an independent study app for learners who want to understand how SQL queries work, not just memorize syntax. It is built for beginners, students, analysts, developers, and interview candidates who need structured practice across fundamentals, practical skills, common pitfalls, and advanced concepts.

Practice through 160 focused questions, each with a clear explanation so you can learn from every answer.

- FSRS spaced-repetition intervals to review at the right time
- Weak-point heatmap to show topics that need attention
- Daily challenge for steady practice
- Mock exams for timed review
- Offline practice for commutes, travel, or quiet study
- No login required

Use it to review SELECT logic, joins, grouping, filtering, NULL behavior, subqueries, set operations, and reasoning patterns that often cause mistakes.
