## Bug Report ### Which version of ShardingSphere did you use? [c20da72](https://github.com/apache/shardingsphere/commit/c20da72e9ecbe8302b7fcc0eb1a60dead97e4854) ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-Proxy ### Expected behavior Show all logic tables when I config same actual table name in different storage unit ### Actual behavior Just show the first logic table now. ``` mysql> show tables like 't_order0'; +-----------------------+------------+ | Tables_in_sharding_db | Table_type | +-----------------------+------------+ | t_order0 | BASE TABLE | +-----------------------+------------+ 1 row in set (0.00 sec) ``` ### Reason analyze (If you can) Then ShardingRule#findTableRuleByActualTable method just consider actual table now. When I config same actual table name in different storage unit, and establish different mapping relationships for actual tables, the logic will be wrong.  ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ```yaml databaseName: sharding_db dataSources: ds_0: url: jdbc:mysql://127.0.0.1:3306/demo_ds_0?serverTimezone=UTC&useSSL=false username: root password: 123456 connectionTimeoutMilliseconds: 30000 idleTimeoutMilliseconds: 60000 maxLifetimeMilliseconds: 1800000 maxPoolSize: 50 minPoolSize: 1 ds_1: url: jdbc:mysql://127.0.0.1:3306/demo_ds_1?serverTimezone=UTC&useSSL=false username: root password: 123456 connectionTimeoutMilliseconds: 30000 idleTimeoutMilliseconds: 60000 maxLifetimeMilliseconds: 1800000 maxPoolSize: 50 minPoolSize: 1 rules: - !SHARDING tables: t_order0: actualDataNodes: ds_0.t_order t_order1: actualDataNodes: ds_1.t_order defaultDatabaseStrategy: none: defaultTableStrategy: none: ``` And then execute following sqls: ```sql -- execute in ds_0 and ds_1 CREATE TABLE `t_order` ( `order_id` bigint(20) NOT NULL, `user_id` int(11) NOT NULL, `status` varchar(50) NOT NULL, `merchant_id` int(11) NOT NULL, `remark` varchar(50) NOT NULL, `creation_date` date NOT NULL, PRIMARY KEY (`order_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 mysql> show tables like 't_order0'; +-----------------------+------------+ | Tables_in_sharding_db | Table_type | +-----------------------+------------+ | t_order0 | BASE TABLE | +-----------------------+------------+ 1 row in set (0.00 sec) mysql> show tables like 't_order1'; Empty set (0.00 sec) ``` ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
