The sql code is as follows：

{code:java}
drop table if exists SourceA;
create table SourceA (
  id    string,
  name  string
) with (
  'connector' = 'kafka-0.11',
  'topic' = 'MyTopic',
  'properties.bootstrap.servers' = 'localhost:9092',
  'properties.group.id' = 'Test',
  'scan.startup.mode' = 'group-offsets',
  'format' = 'csv'
);

drop table if exists print;
create table print (
  id    string,
  name  string
) with (
  'connector' = 'print'
);

drop view if exists test_view;
create view test_view as
select
  *
from SourceA /*+ OPTIONS('properties.group.id'='NewGroup') */;

insert into print
select * from test_view;
{code}
