Re: WHERE statement doesn't work

This artificial code reproduces bug(?):

drop table test_table;
create table test_table (key integer, value integer);
drop table test_table_2;
create table test_table_2 (key integer, value integer);
truncate table test_table;
insert into test_table values (1, 1);
insert into test_table values (2, 1);
insert into test_table values (3, 2);
insert into test_table values (4, 2);

truncate table test_table_2;
insert into test_table_2 values (1, 1);
insert into test_table_2 values (2, 2);

drop view test_table_view;
create view test_table_view as
    select *, row_number() over () as id from test_table;

drop view test_table2_view;
create view test_table2_view as
    select *, row_number() over () as id from test_table_2;


select * from (
    select t.id as id, t2.id as id2     from test_table_view t    join test_table2_view t2        on t.value = t2.value
)
where id2 is not null       and id2 = 1;
