Code analysis is something that looks different than what is being addressed. There is static analysis (a tool similar to the compiler does this in the source code) and the dynamic analysis that tracks the actual execution of the code.
Static code, in a given context, is a term that has little use. It indicates that the code was generated, either manually or automatically (in scaffolding , for example) at development time.
Dynamic code is one that is generated at runtime. This requires that the language and the environment in which it revolves allow this to occur. There are several methods to accomplish this. Some are safer, some are dangerous. Eventually we can say that simple code injection can be a dynamism. But I do not know if it can be applied here if the code was generated earlier.
You may be talking about self modifying code .
In other contexts, it could mean something else.
