Question

if(!"".equals(filterRegistStatus)){
ewStudentFileV.where("REGIST_STATUS_NUMBER = {0}", filterRegistStatus);
}
if(!"".equals(filterLeaveStatus)){
ewStudentFileV.where("LEAVE_STATUS_NUMBER = {0}", filterLeaveStatus);
}
ewStudentFileV.isNull("NATION_NAME");

        用的EntityWrapper类查询，想在最后再加or语句判另一个字段为null(ewStudentFileV.isNull("XXX")),这个or语句怎么加
