一. 安装DBI模块
步骤1：
从TOOLS栏目中下载DBI.zip,下载完后用winzip解开到一个temp目录,共有三个文件：
Readme
DBI.ppd
DBI.tar.gz
步骤2：
在DOS窗口下，temp目录中运行下面的DOS命令：
ppm install DBI.ppd

如果提示无效命令,可在perl/bin目录下运行

二. 安装DBD-Mysql模块
从软件下载中下载DBD-Mysql.zip,安装方法同一.

三. 准备数据库

启动mysql,首先创建一个数据库mydata,然后创建一个表address

mysql> create database mydata;
Query OK, 1 row affected (0.00 sec)

mysql> use mydata;
Database changed
mysql> create table address (
-> id int(5) not null,
-> name varchar(40) not null,
-> email varchar(50) not null,
-> telephone int(12) null);
Query OK, 0 rows affected (0.05 sec)

输入些数据:
mysql> insert into address values (
-> 1,'Nighthawk','nighthawk@163.net',92384092);
Query OK, 1 row affected (0.00 sec)

四. 下面用perl程序来插入若干记录并做查询.

use DBI;

#连接数据库mydata
my $dbh = DBI->connect('DBI:mysql:mydata') or die "无法连接数据库: " . DBI->errstr;

print "插入若干记录\n";
my $sth = $dbh->prepare(q{
INSERT INTO address (id, name,email,telephone) VALUES (?, ?, ?, ?)
}) });

print "输入记录,回车结束:";
while ($inputdata =<>) {
chop $inputdata;
last unless($inputdata);
my ($id, $name,$email, $tel) = split( /,/, $inputdata);
$sth->execute($id, $name, $email,$tel)
}
# $dbh->commit;

print "下面根据输入的名字打印出EMAIL地址和电话\n";
my $sth = $dbh->prepare('SELECT * FROM address WHERE name=?')
or die $dbh->errstr;
print "请输入姓名,回车结束:";
while ($inputname =<>) {
my @data;
chomp $inputname;
last unless($inputname);
$sth->execute($inputname) or die "错误: " . $sth->errstr;
while (@data = $sth->fetchrow_array()) {
print "Email:$data[2]\t Telephone:$data[3]\n";
}
}
#断开连接
$dbh->disconnect;
