in thread Save and Load Data from MySQL DB

I tried this to save:
use strict; use warnings; use Tk; use Tk::JPEG; use DBI; my $datenbank = "bilder"; my $db_host = "localhost"; my $db_port = "3306"; my $db_user = "root"; my $db_pw = "12345"; my $dbh; my $dsn = "DBI:mysql:database=$datenbank;host=$db_host;port=$db_port" +; eval { $dbh = DBI::->connect( $dsn, $db_user, $db_pw, { Raise +Error => 1, PrintError => 0, AutoCommit => 1 } ); }; if ($@) { print DBI::errstr; } my $mw = MainWindow->new(); my $bild = $mw->Photo( -file => "test.jpg" ); $dbh->do("INSERT INTO User (User,Bild) values (?,?)", undef, "2", $bil +d); my $label = $mw->Label(-image => $bild, -background => '#ffffff')->pac +k(); MainLoop;
And this to read:
use strict; use warnings; use Tk; use Tk::JPEG; use DBI; my $datenbank = "bilder"; my $db_host = "localhost"; my $db_port = "3306"; my $db_user = "root"; my $db_pw = "12345"; my $dbh; my $dsn = "DBI:mysql:database=$datenbank;host=$db_host;port=$db_port" +; $dbh = DBI::->connect( $dsn, $db_user, $db_pw, { RaiseError => 1, Prin +tError => 0, AutoCommit => 1 } ); my $mw = MainWindow->new(); my $sql = "SELECT Bild FROM User WHERE User = 2;"; my $sth = $dbh->prepare($sql); $sth->execute; my $bildausdb; ($bildausdb) = $sth->fetchrow_array; my $bild = $mw->Photo( -data => $bildausdb ); my $label = $mw->Label(-image => $bild, -background => '#ffffff')->pac +k(); MainLoop;

    $bild is a TK widget not your image data. Perhaps you need to store that data in the file 'test.jpg' instead?
