[GitHub] [shardingsphere] TeslaCN opened a new issue #14796: ShardingSphere-Proxy empty rule with multiple DataSources cause some problems

TeslaCN opened a new issue #14796:
URL: https://github.com/apache/shardingsphere/issues/14796


   ## Bug Report
   
   ### Which version of ShardingSphere did you use?
   master - 1c844923a9f1da68f8d06934e3ee325f06717bc3
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
   ShardingSphere-Proxy
   
   ### Expected behavior
   I think it's better to forbid configuring multiple DataSources under empty rule schema.
   
   ### Actual behavior
   
   ```
   mysql> use sharding_db;
   Database changed
   
   mysql> create table whereareyou (id bigint primary key, name varchar(100));
   Query OK, 0 rows affected (0.07 sec)
   
   mysql> show tables;
   +-----------------------+------------+
   | Tables_in_sharding_db | Table_type |
   +-----------------------+------------+
   | t_order_item_0        | BASE TABLE |
   | t_order_item_1        | BASE TABLE |
   | whereareyou           | BASE TABLE |
   +-----------------------+------------+
   3 rows in set (0.01 sec)
   
   mysql> insert into whereareyour (id,name) values (1, 'hi');
   ERROR 1146 (42S02): Table 'demo_ds_0.whereareyour' doesn't exist
   
   mysql> create table whereareyou (id bigint primary key, name varchar(100));
   ERROR 1050 (42S01): Table 'whereareyou' already exists
   
   mysql> insert into whereareyour (id,name) values (1, 'hi');
   ERROR 1146 (42S02): Table 'demo_ds_0.whereareyour' doesn't exist
   ```
   
   ### Reason analyze (If you can)
   ![image](https://user-images.githubusercontent.com/20503072/149612108-4e4d82d7-9c21-42bc-a23e-2f21b3f28eb1.png)
   
   DDL was routed to `ds_1` but the insert SQL was routed to `ds_0`.
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   
   ```yaml
   schemaName: sharding_db
   
   dataSources:
     ds_0:
       url: jdbc:mysql://127.0.0.1:3306/demo_ds_0
       username: root
       password: sudo reboot
       connectionTimeoutMilliseconds: 3000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 32
       minPoolSize: 0
     ds_1:
       url: jdbc:mysql://127.0.0.1:3306/demo_ds_1
       username: root
       password: sudo reboot
       connectionTimeoutMilliseconds: 3000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 32
       minPoolSize: 0
   ```

   @TeslaCN The problem was due to a typo, the table name in the statement was misspelled.
