1.创建库（不存在则创建，存在则不创建）

CREATE DATABASE IF NOT EXISTS JIANSHU DEFAULT CHAREST utf8 COLLATE utf8_general_ci

2.选择数据库

use JIANSHU

Create table if not exists ' jianshuarticle ' ( 

'_id' int unsigned auto_increment,

'_title' varchar(100) not null,

'_author' varchar(40) not null,

'submisson_date' DATE,

primary key ('_id')

)ENGINE=InnoDB DEFAULT CHARSET=utf8;

4.增加数据

insert into jianshuarticle ('_title','_author','submisson_date') values ('MySQL的简单使用方法','mister','2017-12-20')

5.删除数据

delete from jianshuarticle 

where _id=1

6.修改数据

update jianshuarticle

set

     submisson_date='2017-12-21'

where 

      name='MySQL的简单使用方法'

7.查询数据

select  _id,_title,_author 

from jianshuarticle

where _id=1 

limit 10;
