创建数据库和模拟数据

1. 创建表

-- t_user 表
CREATE TABLE IF NOT EXISTS `t_user`(
   `id` INT UNSIGNED AUTO_INCREMENT,
   `username` VARCHAR(20) NOT NULL,
   `avatar` VARCHAR(100) NOT NULL,
   `password` VARCHAR(100) NOT NULL,
   `phone` VARCHAR(30) NOT NULL,
   PRIMARY KEY ( `id` )
)

-- t_post 表
CREATE TABLE IF NOT EXISTS `t_post`(
   `id` INT UNSIGNED AUTO_INCREMENT,
   `user_id` INT,
   `title` VARCHAR(100) NOT NULL,
   PRIMARY KEY ( `id` )
)

2. 创建模拟数据

INSERT INTO t_user (id, username, avatar, password, phone) VALUES (1, 'lucus', 'avatar1.png', '111111', '13100000001');
INSERT INTO t_user (id, username, avatar, password, phone) VALUES (2, 'mars', 'avatar2.png', '222222', '13100000002');

INSERT INTO t_post  (id, user_id, title) VALUES (1, 1, '文章1');
INSERT INTO t_post (id, user_id, title) VALUES (2, 1, '文章2');
INSERT INTO t_post (id, user_id, title) VALUES (3, 1, '文章3');
