a cron job needs a perl script to execute

Hello evreyone,

this is my first post, and to say i'm new to this is an understatement.
I know very little about perl scripts and hope some one can help me.
i'm looking to get a script that a cron job can execute.

what the script needs to to is
1) connect to a mysql database
2) go to a table called products
3) grab the products marked as free and 1 week old and delete that record from the table

Since the products are added on a daily bassis, it would be nice to run the cron job every day.

the database reads
free products are marked as ( prodtype )
creation date is marked as ( proddate )
and there is one called ( timetolive )

So far by reading what i can i have the perl script started.

-----------------------------------------
#!/usr/bin/perl

# PERL MODULES WE WILL BE USING
use DBI;
use DBD::mysql

# CONFIG VARIABLES
$platform = "mysql";
$database = "nameofdatabase";
$host = "mysql.domainname.com";
$port = "3306";
$tablename = "products";
$user = "myusername";
$pw = "password";

# DATA SOURCE NAME
$dsn = "dbi:mysql:$database:$host:3306";

# PERL DBI CONNECT
$connect = DBI->connect($dsn, $user, $pw);

}

-------------------------------------------

Now from what i know this could be all wrong

the path to the file that the cron job follows is
/home/myusername/domainname.com/cgi-bin/nameofscript.pl

i also need to use a crontab to set up the daily time to execute the perl script.


please be gentle, I bow down to Newbies Smilie

DBIx::Class::Storage::DBI::mysql(3)			User Contributed Perl Documentation		       DBIx::Class::Storage::DBI::mysql(3)

NAME
DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics SYNOPSIS
Storage::DBI autodetects the underlying MySQL database, and re-blesses the $storage object into this class. my $schema = MyDb::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } ); DESCRIPTION
This class implements MySQL specific bits of DBIx::Class::Storage::DBI, like AutoIncrement column support and savepoints. Also it augments the SQL maker to support the MySQL-specific "STRAIGHT_JOIN" join type, which you can use by specifying "join_type => 'straight'" in the relationship attributes It also provides a one-stop on-connect macro "set_strict_mode" which sets session variables such that MySQL behaves more predictably as far as the SQL standard is concerned. STORAGE OPTIONS
set_strict_mode Enables session-wide strict options upon connecting. Equivalent to: ->connect ( ... , { on_connect_do => [ q|SET SQL_MODE = CONCAT('ANSI,TRADITIONAL,ONLY_FULL_GROUP_BY,', @@sql_mode)|, q|SET SQL_AUTO_IS_NULL = 0|, ] }); AUTHORS
See "CONTRIBUTORS" in DBIx::Class LICENSE
