<p>作为一个前端出身的，也是强行做一波后台需求。。。。最基础的就是建数据表了吧，整个项目下来，大概就用了这些命令，做个笔记，以便备忘。各路大神勿喷。。。。。</p>

<pre>
|
|
create table star_user(
|
|
id int unsigned not null primary key auto_increment,
|
|
username char(20) not null default '',
|
|
login_ip varchar(30) not null,
|
|
`lock` tinyint(1) unsigned not null default 0,
|
|
`fc_msg` text NOT NULL,
|
|
`msg_dttm` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
|
|
`ir_msg_detail` tinytext NOT NULL,
|
|
`ir_func_seq` smallint(3) NOT NULL,
|
|
unique(username)
|
|
) engine myisam default charset utf8;
|
|
</pre>
|
|
<pre>insert into star_user set password = md5('admin'), login_time = unix_timestamp(now());</pre>
|
|
<pre>delete from star_user where login_time = 0;</pre>
|
|
<pre>truncate table star_blog; -- 清空数据库</pre>
|
|
<pre>alter table star_ip_list add p_times int unsigned not null default 0; -- 修改表结构</pre>
|
|
<pre>update `vote`.`star_blog` set `href` = 'http://uzone.univs.cn/blog/4465172.html' where `star_blog`.`id` =21; -- 更新数据</pre>
|
|
<p>其他的比如 use \ show \ desc \ drop 之类的，很常用就不加例子了。</p> |
