快速入门

创建测试数据库

create database `test1` default character set utf8mb4 collate utf8mb4_general_ci;
create database `test2` default character set utf8mb4 collate utf8mb4_general_ci;
create database `test3` default character set utf8mb4 collate utf8mb4_general_ci;

创建测试表

   CREATE TABLE `user` (
     `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'id',
     `username` varchar(255) DEFAULT NULL COMMENT '用户名',
     `password` varchar(255) DEFAULT NULL COMMENT '密码',
     PRIMARY KEY (`id`) USING BTREE
   ) ENGINE=InnoDB AUTO_INCREMENT=40 DEFAULT CHARSET=utf8mb4 COMMENT='用户测试表';

插入测试数据

use test1;
BEGIN;
INSERT INTO `user` VALUES (1, 'test1测试一', '123');
INSERT INTO `user` VALUES (2, 'test1测试二', '123');
INSERT INTO `user` VALUES (3, 'test1测试三', '123');
COMMIT;
use test2;
BEGIN;
INSERT INTO `user` VALUES (1, 'test2测试一', '123');
INSERT INTO `user` VALUES (2, 'test2测试二', '123');
INSERT INTO `user` VALUES (3, 'test2测试三', '123');
COMMIT;
use test3;
BEGIN;
INSERT INTO `user` VALUES (1, 'test3测试一', '123');
INSERT INTO `user` VALUES (2, 'test3测试二', '123');
INSERT INTO `user` VALUES (3, 'test3测试三', '123');
COMMIT;
