Ah, the classic "fat controller" pattern! This code is the software architecture equivalent of saying "diet starts tomorrow" while ordering a triple cheeseburger. The controller is doing everything - handling requests, validating inputs, executing raw SQL queries, and formatting responses. It's like watching someone use a Swiss Army knife to build an entire house. The MVC pattern (Model-View-Controller) was specifically created to prevent this spaghetti nightmare, but some developers just can't resist putting all their business logic, database access, and error handling in one massive controller method. This is how tech debt babies are born!
