You are using function names for virtual member names so ODB tries to
derive modifier names from these function names which is not what you
want. Try to change this to:

#pragma db member(ResultFloatSeven::Id_) virtual(int)
#pragma db member(ResultFloatSeven::Value_) virtual(float)

Also, I don't think you need to go through the virtual member route
in this case. ODB should be able to map everything automatically with
just:

typedef Result<float, 7> ResultFloatSeven;
#pragma db value(ResultFloatSeven) definition
