What it does
PostgreSQL Exercises offers SQL practice covering basic queries, joins, aggregates, window functions and recursion.
Read Getting Started to understand the shared dataset, then choose an exercise category. Reusing one dataset lets you concentrate on the query technique instead of learning a new scenario each time. The site positions itself beside a book or PostgreSQL documentation, making it a practice companion to more explanatory study. Site content is licensed under CC BY-SA 3.0.
