URL: https://github.com/apache/shardingsphere/issues/22359
### Which version of ShardingSphere did you use?
we find java version: java8, full_version=1.8.0_342, full_path=/home/peilq_sharding/bisheng-jdk1.8.0_342//bin/java
ShardingSphere-5.2.2-SNAPSHOT
Commit ID: dirty-753c0cee8ee6fd3db00536da55b64bc5198a3758
Commit Message: Optimize sqlFederationExecutor init logic when sqlFederationType modify dynamically (https://github.com/apache/shardingsphere/pull/22209)
Branch: https://github.com/apache/shardingsphere/commit/753c0cee8ee6fd3db00536da55b64bc5198a3758
Build time: 2022-11-19T10:18:41+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
The select syntax of ‘natural join’ can be excute successfully.
### Actual behavior
The select syntax of ‘natural join’ doesn't supported；
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
```
DROP TABLE IF EXISTS t_order;
DROP TABLE IF EXISTS t_order_item;
CREATE TABLE t_order (order_id INT PRIMARY KEY, user_id INT NOT NULL, status VARCHAR(50) NOT NULL, merchant_id INT NOT NULL, remark VARCHAR(50) NOT NULL, creation_date DATE NOT NULL);
CREATE TABLE t_order_item (item_id INT PRIMARY KEY, order_id INT NOT NULL, user_id INT NOT NULL, product_id INT NOT NULL, quantity INT NOT NULL, creation_date DATE NOT NULL);
INSERT INTO t_order VALUES(1000, 10, 'init', 1, 'test', '2017-07-08');

@peilinqian Can you provide some description about natural join? If we don't know its function, we can't implement it.
