> 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)
