Préfère le versioning par URL (`/v1/`) si ton API est publique et que tu veux une visibilité immédiate pour les développeurs ; le header (`Accept: version=2`) est plus propre pour les APIs internes, mais complexifie la découverte automatique via Swagger.

Prompt ChatGPT to Generate SQL Queries
Generating SQL queries is an essential skill for any developer, data analyst, or database administrator. However, writing complex queries involving multiple joins, nested subqueries, or aggregate functions can be time-consuming and error-prone. ChatGPT transforms this practice radically by allowing you to describe your needs in natural language to obtain optimized and functional SQL queries in seconds. Whether you work with MySQL, PostgreSQL, SQL Server, or SQLite, the AI adapts to the specific syntax of your database management system. By providing your table schema and a clear description of what you want, you can generate perfectly structured SELECT, INSERT, UPDATE, or DELETE queries. ChatGPT also excels at line-by-line explanations of generated queries, making it a valuable learning tool for beginners and professionals alike who wish to explore advanced SQL features like CTEs, window functions, or recursive queries.
