How can I solve this ODE equation?

I have variable "Y" which is dependent on single variable "x". I want to solve following equation:

d(Y(x))/dx==0

It looks simple. I don't have any initial or boundary conditions.

I just found that it can be easily solved using solve() function.

It simply integrates to an arbitrary constant.
