## 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/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 anymore 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? 4.1.1 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior routeValue = 'DS632624670761930754' ### Actual behavior routeValue = '2021-10-23 01:59:44.034' ### Reason analyze (If you can) Version 3.1.0 is no problem ，But upgrading to 4.1.1 fragmented routing has problems I tried to experiment with several schemes， Finally, tracking and debugging found， If I only use the case when statement to update, there is no problem, if the non-case when statement is added, the fragmentation strategy will drift。 It feels like gmt_modify =? Caused by re-marking, ParameterMarkerExpressionSegment(startIndex=339, stopIndex=339, parameterMarkerIndex=1) Theoretically, parameterMarkerIndex should be 0 ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. #分片策略 shardingRule: tables: t_asset_detail: actualDataNodes: ds$->{0..13}.t_asset_detail databaseStrategy: inline: shardingColumn: asset_item_no algorithmExpression: ds$->{Math.abs(asset_item_no.hashCode() % 14)} bindingTables: - t_asset_detail **Error example** UPDATE t_asset_detail SET holder = CASE WHEN asset_item_no = ? AND ? >= gmt_holder THEN ? ELSE holder END , gmt_modify = ? WHERE asset_item_no = ? AND is_deleted = 0 Parameters: DS632624670761930754(String), 2021-10-23 01:50:21.416(Timestamp), 4(Integer), 2021-10-23 01:50:21.416(Timestamp), DS632624670761930754(String) **Normal example** UPDATE t_asset_detail SET holder = CASE WHEN asset_item_no = ? AND ? >= gmt_holder THEN ? ELSE holder END WHERE asset_item_no = ? AND is_deleted = 0 Parameters: DS632624670761930754(String), 2021-10-23 01:50:21.416(Timestamp), 4(Integer), DS632624670761930754(String) ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
