This is not an updateable view in any database product.
It is a cartesian product join of t1 and t2.

You probably wanted:
create view v1 as
select * from t1
union all
select * from t2;

> insert into v1 values(1,'wan1');
> insert into v1 values(12,'wan12');

Version 7.1 will give you an error if you don't create an appropriate
insert and update rule for the view.

Insert and update rules are not yet automatically created for views.
