MySQL Masterclass: How to Set a Custom Starting Value for AUTO_INCREMENT IDs

By default, MySQL auto-incrementing IDs start at 1. However, sometimes we need to reserve a specific range for IDs, for instance, starting from 101. This article provides a deep dive into setting a custom starting value for an `AUTO_INCREMENT` column, both when creating a new table (using DDL) and modifying an existing one (using ALTER TABLE). We offer clear code examples and, from the perspective of architect DP, analyze common scenarios and best practices for reserving IDs to help you build more robust and scalable database models.
