Exploring generic data read functions
Throughout the execution of your programs, you will often want to query the database and return a single value only. Writing individual functions for this can result in a lot of code, making the application bloated and causing future maintenance to be problematic due to duplicated code. As a developer, your main goal is to create small and efficient code to generate accurate results. Developing small and flexible functions that are callable from any other code will help you to achieve this goal. For example, we can create a read function that is designed to read data from our MySQL database. This will allow you to call a single function every time you need to read data, reducing code repetition and improving development efficiency. This process can be applied with other functions, such as read, update, and insert, allowing us to complete these operations in multiple areas without repeating code.
