Stored Routines

Abstract

Throughout this book you’ve seen quite a few examples where the MySQL queries were embedded directly into the PHP script. Indeed, for smaller applications this is fine; however, as application complexity and size increase, continuing this practice could be the source of some grief. For instance, what if you have to deploy two similar applications, one desktop-based and the other Web-based, that use the MySQL database and perform many of the same tasks? On the occasion a query changed, you’d need to make modifications wherever that query appeared not in one application but in two!
