You missed "srno":

with ins_test as (select 1 as srno
union
select 2)
select srno into test from ins_test;
       ^^^^

You can also "select from tbl;" -- omitting the target list.

The easier way to get a table without columns, but with rows is this:

create table test();
insert into test default values;
insert into test default values;
