Disclosure: I help build these simulators; they are part of 50+ free DevOps games and simulators. For more practice beyond them, SQLBolt and PostgreSQL Exercises are excellent and free, and SQL Murder Mystery is the most fun anyone has ever had with a schema. - Source: dev.to / 3 days ago

To overcome these challenges, I relied on SQL documentation, online tutorials, and practice sites like DataLemur and SQLBolt. These resources were invaluable in helping me build confidence and refine my skills. - Source: dev.to / 9 months ago
SQLBolt focuses exclusively on giving you hands-on practice with increasingly complex queries. The platform starts with simple SELECT statements and progressively moves to complex joins and subqueries. You'll get immediate visual feedback while the site explains concepts briefly before each practice section. - Source: dev.to / over 1 year ago

Cool. How does this compare to SafeQL, PgTyped, and Postgres language server ? Source: about 3 years ago
Anyways, an alternative if you're interested in using raw sql for max efficiency is an interesting project called SafeQLwhich treats inline queries as something to be linted. The only issue with that is if you develop on Windows, it doesn't work unless you're using WSL. Source: about 3 years ago
If you want to just write raw/valid SQL safely - SafeQL is great, one major issue though is that it doesn't work on Windows (you can hack it with WSL). Source: over 3 years ago
SafeQL I think could replace a lot of ORM code, the only issue is it doesn't support Windows if you need that. Source: over 3 years ago
