Update Person Fields

Hi,

 

I want to update for all Person its Fields Checkbox-Fields to true. I have tried with searchEngine:

SearchEngine seTest;
seTest.addData("udcontactSmall.long06", "1");
seTest.update();

String msg08="";
SearchEngine seTest2;
seTest2.addField("person.person_id");
seTest2.addField("person.firstname");
seTest2.addField("person.lastname");
seTest2.addField("person.userdef_id.long06");
for (seTest2.execute(); !seTest2.eof(); seTest2.next()){
msg08+= seTest2.getField(0) + "; " + seTest2.getField(1) + "; " + seTest2.getField(2) + "; " + seTest2.getField(3) + "\r\n";
i++;
}
print(msg08);

but it shows not all has this Fileds True, no matter it's Person or User:
