PostgreSQL Exercises features and specs

  • 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 of PostgreSQL Exercises

  • 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  • Outdated design and interface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.

  • Easy to Set-up and use
  • Clean UI
  • Free Trial

  • AI assistance in Development
    With this, I went for designing the db. I went to http://drawsql.app/ and created my first draft. Then exported the DDL and did a bit of back and forth with AI. This is the final draft of the database:. - Source: dev.to / 9 months ago
  • How Changing Requirements Shape the Infrastructure of a Software Project
    So I started designing the DB using this cool tool. The project has 2 tables, users and categories . The user can create many categories as he wants so the first approach I took was creating a third table, a union table to store user_id and category_id. With this solution the users are able to create x numbers of categories and we can see assign the category to the user. - Source: dev.to / over 1 year ago

  • Newbie: Trying to use Supabase Auth fully with its database.
    To be honest, since you are just getting started, I think you should reconsider simplifying this app to begin with. Built something easier and get some more experience before jumping in the ocean. Maybe start by focusing only on the parent company and sub-companies. However, I strongly recommend you to try and make a diagram of your database with relations and columns as it can you a lot of time. I personally use... Source: about 3 years ago
