It uses DBI perl module. You can get more information about DBI module by visiting
Changing the variables, try and see how is it easier.


use DBI;
use strict;

my $DB_NAME = 'nipuna';
my $USER_NAME = 'root';
my $PASSWORD = '';

my $dbh = DBI->connect('DBI:mysql:$DB_NAME','$USER_NAME','$PASSWORD',{RaiseError => 1});

print "Sccessfully connected to the database! \n";
my $sql = "CREATE TABLE tblTest(fname varchar(30), age int(2))";
my $query = $dbh->do($sql);
if ($query == 0){
print "Table was created\n";
print "Not created\n";

Following script explain how to execute a MySQL query using perl script.


use DBI;
use strict;

my $DB_NAME = 'nipuna';
my $USER_NAME = 'root';
my $PASSWORD = '';

my $dbh = DBI->connect('DBI:mysql:$DB_NAME','$USER_NAME','$PASSWORD',{RaiseError => 1});

print "Sccessfully connected to the database! \n";
$query = $dbh->prepare("SELECT * FROM tblTest");
if (defined($query)){
print "Could not execute the query! \n";
my @row;
while (@row = $query->fetchrow_array()){
print "$row[2]\n";

Beryl Intel and debian Linux

I installed the beryl on deban linux system in the following way. It's the easiest way that ever I found.
my graphic card drivers is Intel Corporation 82915G/GV/910GL Integrated Graphics Controller. First you should install the kernel header file to your computer using

apt-get update
apt-get install linux-headers-2.6.*-*-*

* Should be replaced by your kernel version, (take it using uname -r)

After that using modprobe command select your driver modules or go to the and find the Linux driver for your graphic card, it is a must, otherwise Beryl is not working. Xgl and other OpenGL libraries are prerequisites.

Then install Beryl using apt-get, put following in /etc/apt/source.list file and configure the xorg.conf file
deb etch main
deb-src etch main

Here is my xorg.conf
