While the code of this method is:
public List getAll() {
List lstResult = null;

try {
Query query = getSession().createQuery("SELECT * FROM WwsecPerson");
lstResult = query.list();
}
catch (Exception ex) {
System.out.println("Exception: " + ex.getMessage());
}
return lstResult;
}


Does Hibernate allow get data from a table contain $ character?
