### Reason analyze (If you can)
The mysql protocol converts `t_order_FEDERATE` to `t_order_federate`, causing an exception to be thrown during execution.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
Create a table with an uppercase table name in the database, and then write a program to connect to Proxy.
The program can refer to issues #11757.
### Example codes for reproduce this issue (such as a github link).
