### Which version of ShardingSphere did you use?
we find java version: java8, full_version=1.8.0_282
ShardingSphere-5.1.3-SNAPSHOT
Commit ID: dirty-635d9db1bc423ad1d55d6f986d71bc2b47acf922
Commit Message: Fix RUL DistSQL execution failure in transaction(#19831) (#19834)
Tag: 5.2.0
Build time: 2022-09-01T18:55:02+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
### Expected behavior
alter view .. rename to ..，new view name is not configured with broadcast rule；alter failed
### Actual behavior
alter view .. rename to ..，new view name is not configured with broadcast rule；alter succeeded
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
--create
drop view if exists t_broadcast_view;
drop view if exists t_broadcast_view_new;
drop table if exists t_broadcast;
create table t_broadcast(id int,c_id int,a int,b char(10));
insert into t_broadcast values (1,1,10,'test11'),(1,2,10,'Test12'),(1,2,null,'test12'),
(2,1,20,'test21'),(2,2,20,'test22'),(2,3,null,'Test22'),
(3,3,null,'test3'),(3,3,null,'test3'),(4,4,40,'test4'),(5,5,50,'');
--create view；expect：succes
alter sharding broadcast table rules (t_broadcast,t_broadcast_view);
create view t_broadcast_view as select * from t_broadcast;
select * from t_broadcast_view where id=4;
--alter view .. rename to ..，new view name is not configured with broadcast rule；
alter view t_broadcast_view rename to t_broadcast_view_new;
--drop new view ；
drop view t_broadcast_view_new; **--only one DataSource dropped**
