Greetings, Perl Monks.

I have a perl script that connects to an SQL database and adds a new row to it: 

$dbh = DBI->connect("DBI:$driver:$database:$server:$port",$db_user,$db
+_pass);
              die "DBI error from connect:", $DBI::errstr unless $dbh;
$sth = $dbh->prepare($command);
           die "DBI error with prepare:", $sth->errstr unless $sth;
$command = "insert into cardbase (id, picture) values ('".$id."', '".$
+picture."')";
           
$result = $sth->execute;
         die "DBI error with execute:", $sth->errstr unless $result;

$sth->finish;
$dbh->disconnect;

&success;

For this script to work smoothly, I need this particular operation to succeed all the time. However, on some occassions, I run the script, get the &success page but nothing's been added to the sql table. I wonder if there's a way in Perl to find out if an insertion of data was successful, such that (hypothetically): 
if ($insert_ok) {
&success;} else
{&failure;}

Thank you for your time and help:-)

Note of THANKS:

Thanks Taulmarill, ehdonhon and jeffa for your help! I looked into your suggestions and they really helped me solve my problem.
