前言
经常听说删库跑路这真的不只是一句玩笑话,若不小心删除了数据库,事情很严重。你一个不小心可能会给公司删没。建议研发不要直连生成环境,一般的话都会分配账号权限,生产环境的账号尽量是只读,以防你一个不经意给库或表删除。一定要备份,这很重要,这是一个血的教训。
1、创建表
DROP TABLE IF EXISTS `user_misjudge`; --如果表存在则删除,然后执行如下语句重新创建。 CREATE TABLE
`user_misjudge` ( `id` bigint(50) NOT NULL AUTO_INCREMENT, `attr1` varchar(255)
CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL, `attr2`
varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT
NULL, `attr3` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci
NULL DEFAULT NULL, `attr4` varchar(255) CHARACTER SET utf8mb4 COLLATE
utf8mb4_general_ci NULL DEFAULT NULL, `attr5` varchar(25
