DB FiddleRun an example query using Postgres build JSON object

The DB Fiddle plugin lets users run SQL against a disposable sandbox environment, directly from ChatGPT and Codex. Create database schemas, load sample data, execute queries, and inspect real database results without connecting to a production database or external system. The sandbox provides the perfect place for ChatGPT and Codex to iterate on queries and safely debug SQL, reproduce database issues, validate queries and experiment with any of the supported database engines. Supported database engines: PostgreSQL, MySQL, MariaDB, SQLite and more. Note: A db-fiddle.com PRO subscription is required to use this plugin.
