Hi gurus


So I have a problem sending data to MySQL database. Here is my PERL test script:


---------------------- SCRIPT START ----------------------

#!/usr/bin/perl -w


use Net::MySQL;
use strict;
use IO::Socket;
srand;

my $i=0;

my $mysql = Net::MySQL->new(
        hostname => '127.0.0.1',
        database => 'test',
        user => 'root',
        password => ''
);

#INSERT

for ($i=1; $i < 4 ; $i++)
{
print "Line number:\t $i\n";

my $a=int(rand(10))+1;
my $b=int(rand(16))+1;
my $c=int(rand(34))+1;

$mysql->query(q{
INSERT INTO testi (eka, toka, kolmas) values ($a, $b, $c)
});
$mysql->close;
}


---------------------- SCRIPT END ----------------------

And the errors iut gives me when I try to run it:


---------------------- ERROR ----------------------


-bash-2.05b$ ./PERLTESTI
Line number:     1
Line number:     2
getpeername() on closed socket GEN0 at /usr/lib/perl5/5.8.0/i386-linux-thread-multi/IO/Socket.pm line 199.
send: Cannot determine peer address at /usr/lib/perl5/site_perl/5.8.0/Net/MySQL.pm line 277


---------------------- ERROR END ----------------------


I can input data to database from the >MySQL command line so its works fine.


Versions that are in use:
mysql  Ver 12.22 Distrib 4.0.18, for pc-linux (i686)
perl, v5.8.0 built for i386-linux-thread-multi



Any help ?

You should probably check the return value from the "new" call. It's possible that you are simply failing to connect to the database.

Is there a good reason why you're not using DBI and DBD::mysql?
