首先创建数据库：pinghui，数据表：comment(记录留言)。
数据库结构如下：
复制代码 代码如下:
+-----------+-------------+------+-----+---------------------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+-------------+------+-----+---------------------+----------------+
| userid | int(11) | | PRI | 0 | auto_increment |
| username | char(20) | | | | |
| sex | char(2) | | | | |
| address | char(40) | YES | | NULL | |
| ip | char(15) | | | | |
| post | int(11) | YES | | 0 | |
| oicq | int(11) | YES | | 0 | |
| icq | int(11) | YES | | 0 | |
| telnumber | char(30) | YES | | NULL | |
| comment | text | | | NULL | |
| time | datetime | | | 0000-00-00 00:00:00 | |
+-----------+-------------+------+-----+---------------------+----------------+
以上结构的数据库创建
脚本：
复制代码 代码如下:
DROP DATABASE IF EXISTS pinghui;
CREATE DATABASE pinghui;
USE pinghui;
CREATE TABLE comment(
userid int NOT NULL DEFAULT 0 AUTO_INCREMENT PRIMARY KEY,
username char(20) NOT NULL,
sex char(2),
address char(40),
ip char(15) NOT NULL,
post int DEFAULT 0,
oicq int DEFAULT 0,
icq int DEFAULT 0,
telnumber char(30),
comment text NOT NULL,
time datetime NOT NULL
);
INSERT INTO comment (username,ip,comment,time) VALUES ("pinghui","127.0.0.1",
"你好，请到脚本学习网查看信息！",now());
insert into comment (username,sex,address,ip,post,oicq,icq,telnumber,comment,time)
values ('pinghui','男','地址','127.0.0.1',250100,2269101,74875874,'0531-1234567',
'你好，请到脚本学习网查看留言！谢谢！',now());
