2020年全国计算机二级MySQL复习知识点：Perl连接Mysql数据库的方法思维导图

网站后台数据库转为Mysql，现在使用Perl连接数据库就方便多了。

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->{'name'}\n";

$dbh->disconnect();

执行结果:

[root@eygle ~]# perl test.cgi
