How do programmers practice code reuse

Question

I\'ve been a bad programmer because I am doing a copy and paste. An example is that everytime i connect to a database and retrieve a recordset, I will copy the previous code and

Answer 1

I'll do this at two levels. First within a class or namespace, put that code piece that is reused in that scope in a separate method and make sure it is being called.

Second is something similar to the case that you are describing. That is a good candidate to be put in a library or a helper/utility class that can be reused more broadly.

It is important to evaluate everything that you are doing with an perspective whether it can be made available to others for reuse. This should be a fundamental approach to programming that most of us dont realize.

Note that anything that is to be reused needs to be documented in more detail. Its naming convention be distinct, all the parameters, return results and any constraints/limitations/pre-requisites that are needed should be clearly documented (in code or help files).
