MySQL示例数据库

本帖是为【】的学习过程中建立一个事例数据库，并提供创建事例表的SQL语句和相关数据。

1.创建样例数据库

sql 复制代码

CREATE DATABASE IF NOT EXISTS 一轮;
use 一轮;

2.创建表

sql 复制代码

create table if not exists table_01(
  id INT primary key,                 #id
  create_time DATETIME not null,       #创建时间
  modification_time DATETIME not null, #修改时间
  is_delete tinyint not null,          #是否删除
  content text
) 
create table if not exists table_02(
  id INT primary key,                 #id
  create_time DATETIME not null,       #创建时间
  modification_time DATETIME not null, #修改时间
  is_delete tinyint not null,          #是否删除
  content text
)

创建之后的表就是这样的：

3.这里在表中插入若干条数据

sql 复制代码

INSERT INTO table_01 VALUES
(2, '2026-01-30', '2026-01-30', 0, '小李飞刀'),
(3, '2026-01-29', '2026-01-29', 0, '楚留香传奇'),

插入之后就变成了这样：
