Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? 5.0.0-RC1-SNAPSHOT ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior Under MasterSlave rule: `SELECT * FROM t_order WHERE user_id = ? FOR UPDATE` should be routed to Master node ### Actual behavior The SQL is routed to Slave node ### Reason analyze (If you can) LockSegment absent of PostgreSQL parser Please refer to the route logic in MasterSlaveDataSourceRouter: ``` private boolean isMasterRoute(final SQLStatement sqlStatement) { return containsLockSegment(sqlStatement) || !(sqlStatement instanceof SelectStatement) || MasterVisitedManager.isMasterVisited() || HintManager.isMasterRouteOnly(); } private boolean containsLockSegment(final SQLStatement sqlStatement) { return sqlStatement instanceof SelectStatement && ((SelectStatement) sqlStatement).getLock().isPresent(); } ``` ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ### Example codes for reproduce this issue (such as a github link). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
