使用Perl连接Mysql数据库

通过DBI，Perl可以很容易的连接到数据库:

#!/bin/perl

use DBI;

# Connect to target DB
my $dbh = DBI->connect("DBI:mysql:database=eygle;host=localhost","username","password",{'RaiseError' => 1});

# Insert one row?
my $rows = $dbh->do("INSERT INTO test (id,name) VALUES (1,'eygle')");

# query?
my $sqr = $dbh->prepare("SELECT name FROM test");
$sqr->execute();

while(my $ref = $sqr->fetchrow_hashref()) {
??? print "$ref->n";
}

$dbh->disconnect();

执行结果:

[root@eygle ~]# perl test.cgi?
eygle

以后很多统计数据可以直接通过Perl写入Mysql数据库，操作起来方便多了。
