Sorry, I don't understand what you mean by `default logical table`.
[Here](https://shardingsphere.apache.org/document/current/en/user-manual/shardingsphere-proxy/distsql/usage/sharding-rule/) is an example of creating a sharding table rule via DistSQL.

@RaigorJiang
I know the cause of the problem "The logical database has disappeared".
When the rule configuration of one logical database is incomplete, all other logical database disappear.
Such as：
create database ds;
use ds;
```
ADD RESOURCE ds_abc (
HOST=192.168.0.1,
PORT=3306,
DB=ds_abc,
USER=root,
PASSWORD=123456
);
ADD RESOURCE ds_bcd (
HOST=192.168.0.1,
PORT=3306,
DB=ds_bcd,
USER=root,
PASSWORD=123456
);
CREATE SHARDING ALGORITHM database_inline (
TYPE(NAME=inline,PROPERTIES("algorithm-expression"="ds_${tenant_code}"))
);
CREATE DEFAULT SHARDING DATABASE STRATEGY (
TYPE = standard,SHARDING_COLUMN=tenant_code,SHARDING_ALGORITHM=database_inline
);
==================================================================
CREATE SHARDING TABLE RULE order_test (
datanodes("ds_${['abc','bcd']}.order_test")
)
CREATE SHARDING TABLE RULE user_test (
datanodes("ds_${['abc','bcd']}.user_test")
)
```
This occurs when the rules for the logical table have not been configured.

Does DistSql support concurrent manipulation of logical resources?
For example, one thread adds a logical database resource and another thread modifies another logical database resource.
Will the same happen with DistSql？ refer to https://community.sphere-ex.com/t/topic/1053

DistSQL provides an API for managing ShardingSphere configuration, which has been carefully designed and tested, and also has validation logic during execution.
However, directly modifying the ZK node is not a supported method. There is no test case covering this scenario, which is not recommended.

So, this issue is not clearly described (including the screenshot you provided), and it doesn't match the title.
I suggest you change the title and clarify the content, or submit another issue.
In addition, if you want to ask how to write DistSQL, please provide the complete YAML configuration, an incomplete screenshot cannot provide complete information.

The schema version is used to switch metadata, such as scaling, DistSQL will not directly change the schema version, which is determined by the governance feature.
