mysql表名字段名批量改小写

本文主要是介绍mysql表名字段名批量改小写，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1. 导出sql 如

   CREATE TABLE `act_evt_log` (
     `LOG_NR_` bigint(20) NOT NULL AUTO_INCREMENT,
     `TYPE_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `PROC_DEF_ID_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `PROC_INST_ID_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `EXECUTION_ID_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `TASK_ID_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `TIME_STAMP_` timestamp(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) ON UPDATE CURRENT_TIMESTAMP(3),
     `USER_ID_` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL,
     `DATA_` longblob,
     `LOCK_OWNER_` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL,
     `LOCK_TIME_` timestamp(3) NULL DEFAULT NULL,
     `IS_PROCESSED_` tinyint(4) DEFAULT '0',
     PRIMARY KEY (`LOG_NR_`) USING BTREE
   ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin ROW_FORMAT=DYNAMIC;
   

2. 要在Vim中执行此操作，请打开文件，然后输入以下命令：

   :%s/`\(\w\+\)`/\L&/g

3. 保存即可

   CREATE TABLE `act_evt_log` (
     `log_nr_` bigint(20) NOT NULL AUTO_INCREMENT,
     `type_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `proc_def_id_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `proc_inst_id_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `execution_id_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `task_id_` varchar(64) COLLATE utf8mb4_bin DEFAULT NULL,
     `time_stamp_` timestamp(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) ON UPDATE CURRENT_TIMESTAMP(3),
     `user_id_` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL,
     `data_` longblob,
     `lock_owner_` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL,
     `lock_time_` timestamp(3) NULL DEFAULT NULL,
     `is_processed_` tinyint(4) DEFAULT '0',
     PRIMARY KEY (`log_nr_`) USING BTREE
   ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin ROW_FORMAT=DYNAMIC;
