## 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/incubator-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 **more than 7 days** 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?
4.0.0-RC2
### Which project did you use? Sharding-JDBC or Sharding-Proxy?
Sharding-Proxy
### Expected behavior
Ability to discover data sources And Execute sql statement without error
### Actual behavior
Execute sql statement error
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
Environmental configuration：
I have two mysql database instances And each instance of the database contains “order_tbl” table.
My ss-proxy configuration:
