   ## 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
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   Sharding-Proxy(docker registry to deploy)
   ### Expected behavior
   more than one database query support order by use string column
   ### Actual behavior
   not support, only support when route one database, cross database support i test is int、datetime etc, if use string column to order by, query sql is always executing, cann't get result or error
   ### Reason analyze (If you can)
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.

   > @xiaoxiong581 what is the version of java?
   
   I use three method to connect Sharding-Proxy Server,like:java code(use jdbctemplate and hikaricp DataSource)、Dbeaver、mysql command in mysql docker, get same result
   java code use 1.8.0_211(Oracle)

   I submit a similar issue a few days ago #4639, but @terrymanu think is invalid.
   but i see document in https://shardingsphere.apache.org/document/current/cn/features/sharding/use-norms/sql/, it support order by query in more than one database

   I have traced the program and found that exception happened in 'org.apache.shardingsphere.core.execute.sql.execute.result.StreamQueryResult'.
   ```
       @Override
       public boolean isCaseSensitive(final int columnIndex) throws SQLException {
           return resultSetMetaData.isCaseSensitive(columnIndex);
       }
   ```
   The information of exception is below:
   java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@3a1741d6 is still active. 
   No statements may be issued when any streaming result sets are open and in use on a given connection. 
   Ensure that you have called .close() on any active streaming result sets before attempting more queries.

   ## 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
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   Sharding-Proxy(docker registry to deploy)
   ### Expected behavior
   more than one database query support order by use string column
   ### Actual behavior
   not support, only support when route one database, cross database support i test is int、datetime etc, if use string column to order by, query sql is always executing, cann't get result or error
   ### Reason analyze (If you can)
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   #### create table sql
   ```sql
   CREATE TABLE t_cluster(
       clusterId VARCHAR(64) NOT NULL   COMMENT '数据库集群ID' ,
       clusterName VARCHAR(128) NOT NULL   COMMENT '数据库集群名称' ,
       projectId VARCHAR(64) NOT NULL   COMMENT '项目ID' ,
       createTime DATETIME NOT NULL   COMMENT '创建时间' ,
       updateTime DATETIME NOT NULL   COMMENT '更新时间' ,
       PRIMARY KEY (clusterId)
   ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT = '数据库集群信息表';
   ALTER TABLE t_cluster ADD UNIQUE index_cluster_unique_name(clusterName);
   ```

   ### Example codes for reproduce this issue (such as a github link).
   #### test sql

   #### enviroment
   table t_cluster no data
   #### expected result
   `return no data`
