FlyingZC opened a new issue, #23929: URL: https://github.com/apache/shardingsphere/issues/23929
## Bug Report 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? master. ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? proxy. ### Expected behavior Drop index successfully when create index does not specify an index name ### Actual behavior Drop index failed. ### Reason analyze (If you can) Maybe the index rewrite does not handle the case without index name. ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ```sql -- 1.create index without index name alter table t_order add index(order_id); -- 2.show create table t_order; | t_order | CREATE TABLE `t_order` ( `order_id` int(11) NOT NULL, `user_id` int(11) NOT NULL, `status` varchar(45) DEFAULT NULL, KEY `order_id` (`order_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 -- 3.drop index with index name `order_id` alter table t_order drop index order_id; ERROR 1091 (42000): Can't DROP 'order_id_t_order_0'; check that column/key exists ``` proxy config ```yaml databaseName: sharding_db dataSources: ds_0: url: jdbc:mysql://127.0.0.1:3306/demo_ds_0?serverTimezone=UTC&useSSL=false&allowPublicKeyRetrieval=true username: root password: x connectionTimeoutMilliseconds: 30000 idleTimeoutMilliseconds: 60000 maxLifetimeMilliseconds: 1800000 maxPoolSize: 50 minPoolSize: 1 ds_1: url: jdbc:mysql://127.0.0.1:3306/demo_ds_1?serverTimezone=UTC&useSSL=false&allowPublicKeyRetrieval=true username: root password: x connectionTimeoutMilliseconds: 30000 idleTimeoutMilliseconds: 60000 maxLifetimeMilliseconds: 1800000 maxPoolSize: 50 minPoolSize: 1 rules: - !SHARDING tables: t_order: actualDataNodes: ds_${0..1}.t_order_${0..1} tableStrategy: standard: shardingColumn: order_id shardingAlgorithmName: t_order_inline keyGenerateStrategy: column: order_id keyGeneratorName: snowflake t_order_item: actualDataNodes: ds_${0..1}.t_order_item_${0..1} tableStrategy: standard: shardingColumn: order_id shardingAlgorithmName: t_order_item_inline keyGenerateStrategy: column: order_item_id keyGeneratorName: snowflake bindingTables: - t_order,t_order_item defaultDatabaseStrategy: standard: shardingColumn: user_id shardingAlgorithmName: database_inline defaultTableStrategy: none: shardingAlgorithms: database_inline: type: INLINE props: algorithm-expression: ds_${user_id % 2} database_id_inline: type: INLINE props: algorithm-expression: ds_${id % 2} t_order_inline: type: INLINE props: algorithm-expression: t_order_${order_id % 2} t_order_item_inline: type: INLINE props: algorithm-expression: t_order_item_${order_id % 2} keyGenerators: snowflake: type: SNOWFLAKE ``` ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
