前两天看到了一篇博客，学习到了通过存储过程批量随机生成用户信息的方法，总结了下，在这里分享给大家，同时也做一个学习记录。闲话不多说，进入正题
我这边使用的是mysql数据库，Navicat12工具，，测试用户信息表d_user表结构如下：
CREATE TABLE `d_user` (`id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '用户主键ID',`user_type` tinyint(1) NULL DEFAULT NULL COMMENT '用户类型',`user_name` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_czech_ci NULL DEFAULT NULL COMMENT '用户名',`age` tinyint(3) NULL DEFAULT NULL COMMENT '年龄',`password` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '密码',`mobile` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '手机号',`email` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '邮箱',`image_url` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '头像地址',`last_online_time` datetime(0) NULL DEFAULT NULL COMMENT '最后上线时间',`status` tinyint(4) NULL DEFAULT 1 COMMENT '状态 0：禁用 1：正常',`salt` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '盐',`create_user_id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '创建人ID',`create_by` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '创建人',`create_time` datetime(0) NULL DEFAULT NULL COMMENT '创建时间',`update_user_id` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '更新人ID',`update_by` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '更新人',`update_time` datetime(0) NULL DEFAULT NULL COMMENT '更新时间',`is_delete` tinyint(2) NULL DEFAULT 0 COMMENT '是否删除 0：不删1：删除',PRIMARY KEY (`id`) USING BTREE) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;SET FOREIGN_KEY_CHECKS = 1;
下面sql内容需要了解到mysql生成随机数相关函数的用法，不了解的可以先了解下哦。。。

存储函数
1.随机生成用户名称generate_userName()

到这里大体部分就已经结束了，，
对于存储过程，存储函数，我这里也附上我参考学习的链接，大家一起做一个回顾学习，如果对以上内容有什么想法，欢迎大家留言，感谢。
