No. It does not need to. I just gave preprocessing as a example.
Let's just assume that the function accepts a parameter. Based on certain condition, it either needs to insert a record or update the existing one.
You can split up the logic of insert and update as two separate function. Here the main function almost acts as a wrapper. The main business logic resides in two different function, which can be reused elsewhere as required.
Hope that helps.
Thank you, that makes much more sense now.
