Bug Report

For English only, other languages will not accept.

Before report a bug, make sure you have:

• Searched open and closed GitHub issues.
• Read documentation: ShardingSphere Doc.

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-RC2

Which project did you use? Sharding-JDBC or Sharding-Proxy?

Sharding-Proxy

Expected behavior

Ability to discover data sources And Execute sql statement without error

Actual behavior

Execute sql statement error

Reason analyze (If you can)

Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.

Environmental configuration：
I have two mysql database instances And each instance of the database contains “order_tbl” table.
My ss-proxy configuration:

schemaName: cyberplus_meta

dataSources:
  cyberplus_meta_instance_1:
    url: jdbc:mysql://localhost:3306/cyberplus_meta_instance_1?useSSL=false&serverTimezone=UTC
    username: root
    password: 123456
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50
  cyberplus_meta_instance_2:
    url: jdbc:mysql://localhost:3306/cyberplus_meta_instance_2?useSSL=false&serverTimezone=UTC
    username: root
    password: 123456
    connectionTimeoutMilliseconds: 30000
    idleTimeoutMilliseconds: 60000
    maxLifetimeMilliseconds: 1800000
    maxPoolSize: 50


shardingRule:
  tables:
    order_tbl:
      actualDataNodes: cyberplus_meta_instance_${1..2}.order_tbl
      databaseStrategy:
        inline:
          shardingColumn: id
          algorithmExpression: cyberplus_meta_instance_${id % 2 + 1}
  defaultDatabaseStrategy:
    none:
  defaultTableStrategy:
    none:
  defaultDataSourceName: cyberplus_meta_instance_1

### Example codes for reproduce this issue (such as a github link).
Executing sql is 
SHOW FULL TABLES FROM `cyberplus_meta` LIKE 'order_tbl'

If you have questions about show tables, please look at this first.

Thank you, may I ask when this pr can be merged into the master branch?

[sunbufu]

The PR is blocked by the refactor of route engine, so please wait patiently.
