Vincent Maverick Durano · Answer

Just like any code. It's recommended to write stored procedure that handle specific job (separation of concerns). This way it's very easy for you to maintain, add or remove logic without impacting your whole script. Think of it as wrting a separate method in your app that calls another method to perform certain tasks. The idea is to minimize code complexity within a method by splitting them up to multiple methods or stored procedures in your case.
