Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? 4.1.0 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-Proxy ### Expected behavior mysql> show databases; +----------+ | Database | +----------+ | db1 | | db2 | +----------+ mysql> use db1; mysql> select * from db2.test_table; ERROR 1146 (42S02): Table 'db2.test_table' doesn't exist ### Actual behavior SQL run well. ### Reason analyze (If you can) sql parser does not extract schema from sql to modify sql statement context. Only "use db2 " can change schema. ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. shardingrule config: any config. ### Example codes for reproduce this issue (such as a github link). use db1; do any sql on db2.table. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
