I've printed the data member path like so:

key = "column-id-type"
data member=::NS1::NS2::BaseClass::id_

namespace NS1 { namespace NS2 {
class BaseClass {
protected:
   std::uint32_t id_;
};
}}

id_ is a protected member of BaseClass and its c++ type is  std::uint32_t

A empty derived class is defined:

> class DerivedClass : public BaseClass {};


The pragmas look like so:

#include "DerivedClass.h"
#pragma db object(BaseClass) polymorphic table("eqlogb") transient
definition
#pragma db member(BaseClass::id_) id unique
#pragma db object(DerivedClass) abstract table("eqlogbl") transient
definition

I have added

> type("INTEGER") and id_type("INTEGER")

to the pragma for id_

The no_entry exception is still thrown.
