[GitHub] [shardingsphere] waterMeteors opened a new issue #6376: ShardingSphere-Proxy Nested query exception in mysql data source

waterMeteors opened a new issue #6376:
URL: https://github.com/apache/shardingsphere/issues/6376


   
   ### Which version of ShardingSphere did you use?
         the version is 4.1.0.
   
   ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
         I user ShardingShpere-Proxy project.
   ### Expected behavior
        Return sql statement to query normal data
   ### Actual behavior
        Return statement is Table 'schemaName.tableName' doesn't exist. for example :'Table 'test.example_order' doesn't exist'.
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
       The sharding rule file is :
   ------------
   schemaName: test
   dataSources:
     ds0:
       url: jdbc:mysql://ip地址:8809/test
       username: root
       password: 密码
       connectionTimeoutMilliseconds: 30000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 50
     ds1:
       url: jdbc:mysql://ip地址:8809/test
       username: root
       password: 密码
       connectionTimeoutMilliseconds: 30000
       idleTimeoutMilliseconds: 60000
       maxLifetimeMilliseconds: 1800000
       maxPoolSize: 50
   shardingRule:
     tables:
       example_order:
         actualDataNodes: ds${0..1}.example_order${0..1}
         tableStrategy:
           inline:
             shardingColumn: order_id
             algorithmExpression: example_order${order_id % 2}
         keyGenerator:
           type: SNOWFLAKE
           column: order_id
     bindingTables:
       - example_order
     defaultDatabaseStrategy:
       inline:
         shardingColumn: user_id
         algorithmExpression: ds${user_id % 2}
     defaultTableStrategy:
       none:
   ------------
   The statement error when i execute "select * from (select * from example_order) aa " in navicat. if i execute "select * from example_order" that is ok. 
   ### Example codes for reproduce this issue (such as a github link).

   I will clone latest source code for dubbug to see the specific reasons. Directly upgrading the version may affect our previous services. Thank you very mach @kimmking

   Hi @waterMeteors 
   Thanks for your feedback. I am afraid `subquery` could not work well at the latest release. If it is available, you'd better debug it on our `master branch` which provides better support for `subquery`.
   
   Welcome your tests.
