## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response anymore and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ### Expected behavior After executing the "create sharding binding table rules (t_ssdb_tb_view, t_ssdb_tb);" statement, the next SQL statement is executed normally ### Actual behavior After executing the "create sharding binding table rules (t_ssdb_tb_view, t_ssdb_tb);" statement, an error will be reported when the next SQL statement is executed ### Reason analyze (If you can) ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ``` drop view if exists t_ssdb_tb_view; drop view if exists t_ssdb_tb_view_new; drop table if exists t_ssdb_tb; create table t_ssdb_tb(id int,c_id int,a int,b char(10)); insert into t_ssdb_tb 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,'Test5');
