You will need to be more specific and precise about what exactly you've
done. In fact, if you really did "rename a field on database" as you say,
then it would have had no effect on anything ODB-related (ODB sees changes
in C++ object model, not in databases).
So what you probably mean is that you have renamed a data member in a
class. Or maybe you have renamed the class itself. Without knowing
exactly what you've done it's hard to say what went wrong.
I suggest that you provide a small step-by-step test that reproduces
the problem. For each step provide the header file to compile and the
ODB command line to compile it.
