四、perl进行MySQL开发实例

上述都安装完后，就可以进行实际开发了。

首先在test数据库中新建一个表

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)

简单的perl代码实例：

#!perl

use DBI;

my $db = "test";

my $host = "localhost";

my $user = "root";

my $pwd = "";

my $connection="dbi:mysql:$db:$host";

my $dbh = DBI->connect($connection,$user,$pwd) or die "failed to connect mysql,$!";

print "插入若干记录\n";

my $sql = "insert into address(id,name,email,telephone) values(?,?,?,?)";

my $sth = $dbh->prepare($sql);

print "输入记录,回车结束:";

while ($inputdata =<>) {

chomp $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";

$sql = "SELECT * FROM address WHERE name=?";

$sth = $dbh->prepare($sql) 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()) {

print "Email:$data[2]\t Telephone:$data[3]\n";

}

}

#断开连接

$sth->finish();

$dbh->disconnect();
