What DB Fiddle does in ChatGPT
The DB Fiddle plugin gives ChatGPT and Codex a throwaway database to run SQL in. You can create tables, load some sample rows, run queries and look at the real results, without touching a production database or any outside system. When you are done, the sandbox can simply be thrown away.
That makes it a safe place to work out a tricky query step by step, reproduce a database bug, check that a query returns what you expect, or try something on a different engine. Supported engines include PostgreSQL, MySQL, MariaDB and SQLite, and the listing says there are more.
You need a paid db-fiddle.com PRO subscription to use the plugin, according to the listing. It is meant for testing and learning, so it does not connect to your own live databases. You can keep iterating on a query in the same sandbox until it does what you want, then copy the final version into your own project.
