Features and specs

What each product offers, as listed by its team.

PostgreSQL Exercises 5 features
SqlInt 3 features
  • Free and accessible
    PostgreSQL Exercises is completely free to use with no registration required, making it highly accessible to anyone who wants to practice SQL skills without any financial barrier.
  • Interactive practice environment
    The site provides a built-in SQL query editor where users can write and execute queries directly in the browser against a real database, getting immediate feedback on their results.
  • Progressive difficulty
    Exercises are well-organized into categories (basic, joins, aggregation, date, string, recursive) and progress from simple to complex, allowing learners to build their skills incrementally.
  • Realistic dataset
    The site uses a realistic country club management scenario with interconnected tables, giving learners practice with a coherent and relatable data model rather than abstract or disconnected examples.
  • Detailed solutions and explanations
    Each exercise comes with a detailed expected result set and a thorough explanation of the solution, helping learners understand not just what the answer is but why it works.

Possible disadvantages

  • Limited dataset scope
    The entire site relies on a single small dataset (a country club with members, facilities, and bookings), which limits exposure to diverse data modeling patterns and real-world complexity.
  • No user progress tracking
    Since there is no account system or registration, the site does not track user progress, making it difficult for learners to pick up where they left off or monitor their improvement over time.
  • PostgreSQL-specific syntax
    The exercises focus specifically on PostgreSQL syntax and features, which may not directly translate to other database systems like MySQL, SQL Server, or Oracle, potentially limiting transferability of learned skills.
  • Outdated design and interface
    The website has a dated visual design and user interface that lacks modern UX features such as syntax highlighting, auto-completion, or responsive mobile support, making it less pleasant to use compared to newer platforms.
  • Limited number of exercises
    The total number of exercises is relatively small compared to other competitive programming or SQL practice platforms, meaning advanced users may quickly exhaust the available problems.
  • Interactive SQL Practice
    Write and run SQL queries in a hands-on environment
  • SQL Puzzles
    Solve interactive challenges that test your SQL problem-solving skills
  • Interview Preparation
    Practice SQL problems designed to build technical interview confidence
