Why ? Why everything is against me ? :)
Well let's tell you. Here is some small code that doesn't work. Very easy, just connect to database MySQL, select, (print), and disconnect. But... It's my first use of DBI and DBD::Mysql.

#! perl -w

use strict;
use DBI;
use DBD::mysql;

# Connect DataBase
my $dbh = DBI->connect('DBI:mysql:CCM', 'root', '');

###### THIS DOESN'T WORK :( #####
# Prepare the SQL query for execution
my $sth = $dbh->prepare(<<End_SQL) or die "Couldn't prepare statement:
+ $DBI::errstr; stopped";
SELECT f1, f2, f3, f4, f5, f6 FROM forum WHERE f1 = 10
End_SQL

###### THIS WORK FINE #####
# my $sth = $dbh->prepare(<<End_SQL) or die "Error: i$DBI::errstr; sto
+pped";
# INSERT INTO forum values(10, "foo", "bar", "foobar", "barfoo", "barb
+ar")
# End_SQL

$sth->execute() or die "Error: $DBI::errstr; stopped";

# Fetch each row and print it
my ($f1, $f2, $f3, $f4, $f5, $f6) = $sth->fetchrow_array();
print STDOUT "$f1 $f2 $f3 $f4 $f5 $f6\n";

my $title = $sth->fetchrow_array();
print $title;

# Disconnect Database
$dbh->disconnect();

In fact, this may work but give me this error message:

DBI::db=HASH(0x1d2bae0)->disconnect invalidates 1 active statement handle (either destroy statement handles or call finish on them before disconnecting) at C:\WINDOWS\Profiles\bob\Desktop\ccm_forum.pl line 32.

That mean on the last line during DISCONNECT(). I don't really understand this message...
So I am searching for enlightement from The God PERL.
Thanks.
