hunter7727 opened a new issue #3064: Cannot find actual datasource intersection for logic tables:["table_name",%] URL: https://github.com/apache/incubator-shardingsphere/issues/3064 ## 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-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 ``````````````````````````````````````````````````````` Error stack information： ````````````````````````````````````````````````` Rule Type: sharding Logic SQL: SELECT * FROM order_tbl LIMIT 1 SQLStatement: ShardingSelectOptimizedStatement(tables=Tables(tables=[Table(name=order_tbl, alias=Optional.absent())], schema=Optional.absent()), groupBy=org.apache.shardingsphere.core.optimize.sharding.segment.select.groupby.GroupBy@4683a848, orderBy=org.apache.shardingsphere.core.optimize.sharding.segment.select.orderby.OrderBy@6d56908d, selectItems=SelectItems(startIndex=7, stopIndex=7, distinctRow=false, items=[ShorthandSelectItem(owner=Optional.absent())], tables=[TableSegment(startIndex=14, stopIndex=22, name=order_tbl, quoteCharacter=NONE, owner=Optional.absent(), alias=Optional.absent())]), pagination=org.apache.shardingsphere.core.optimize.sharding.segment.select.pagination.Pagination@4225d0fc, containsSubquery=false) Actual SQL: cyberplus_meta_instance_1 ::: SELECT * FROM order_tbl LIMIT 1 Actual SQL: cyberplus_meta_instance_2 ::: SELECT * FROM order_tbl LIMIT 1 Rule Type: sharding Logic SQL: SHOW FULL TABLES FROM `cyberplus_meta` LIKE 'order_tbl' SQLStatement: TransparentOptimizedStatement(tables=Tables(tables=[Table(name=order_tbl, alias=Optional.absent())], schema=Optional.absent())) Actual SQL: cyberplus_meta_instance_1 ::: SHOW FULL TABLES LIKE 'order_tbl' [ERROR] 15:34:04.170 [ShardingSphere-Command-14] o.a.s.s.f.c.CommandExecutorTask -
