PERL - MySQL Connect

The MySQL module works only with the MySQL platform. We can maintain the same variables from the previous example to connect to MySQL.

#!/usr/bin/perl

# PERL MODULE
use Mysql;

# HTTP HEADER
print "Content-type: text/html \n\n";

# CONFIG VARIABLES
$host = "localhost";
$database = "store";
$tablename = "inventory";
$user = "username";
$pw = "password";

# PERL MYSQL CONNECT
$connect = Mysql->connect($host, $database, $user, $pw);

If this script was run on your web server through a web browser, you should be starring at a blank white screen and all is well.

PERL - MySQL listdbs()

Once PERL has established a connection we can execute any of the built in module functions. A great introductory function is the listdbs function. This function reads from the MySQL platform and places the name of each database into an array.

@databases = $connect->listdbs;

We can then loop through this array and print out our results to the browser.

#!/usr/bin/perl

# PERL MODULES
use Mysql;

# MYSQL CONFIG VARIABLES
$host = "localhost";
$database = "store";
$tablename = "inventory";
$user = "username";
$pw = "password";

# PERL CONNECT()
$connect = Mysql->connect($host, $database, $user, $pw);

# LISTDBS()
@databases = $connect->listdbs;
foreach $database (@databases) {
	print "$database<br />";
}
