      Description

      Consider following:-

      create table person (
      id varchar(20) not null,
      name varchar(100) not null
      );

      create table car (
      id varchar(20) not null,
      person_id varchar(20) not null,
      model varchar(100) not null,
      plat_no varchar(100) not null
      );

      When select :-
      select
      p.name,
      c.model,
      c.plat_no
      from person p
      left join car c on (p.id = c.person_id);

      From the ResultSet, get the ResultSetMetaData and inspect each column's isNullable() value, which is always = 1 (always nullable). Expected : column 'p.name' isNullable = 0 (not nullable), but I get 'p.name' isNullable = 1 (nullable)
