I'm not quite sure what is unblessed about what reference in my query below. Any ideas? -- Hugh

My code throws these errors: 

$dsn = DBI:mysql(RaiseError => 1):host=localhost.localdomain;database=
+testdb
$dbh = HASH(0x9d44a24)
Can't call method "prepare" on unblessed reference at ./cache-pages.pl
+ line 28.

and reads like this: 
$dbh = ed_connect($conf{'dbversion'}, $conf{'dbhost'}, $conf{'dbname'}
+, $conf{'dbuser'}, $conf{'dbpass'});
print "\$dbh = $dbh \n";

$sql = "SELECT summary FROM mod_article";
$sth = $dbh->prepare($sql);
$sth->execute();
while ($node = $sth->fetchrow_array()) {
  $ed = $node;
  $ed =~ s/^.*(\d{5}).*$/$1/;
  print $ed;
}

exit;
1;

sub ed_connect {
   my($db_version,$host_name,$db_name,$db_user,$db_pass)=@_;
   # my $dsn = "DBI:mysql:host=$host_name;database=$db_name";
   my $dsn = "DBI:$db_version(RaiseError => 1):host=$host_name;databas
+e=$db_name";

   print "\$dsn = $dsn \n";

   return (DBI->connect($dsn,$db_user,$db_pass),
      {PrintError => 1, RaiseError => 1});
}
