Now for the Win32::ODBC version -- less commentary, as it's a little l
+ess flexiable, but more obvious (IMHO):
use Win32::ODBC;

my @rows;

my $DSN = "Name";

if (!($db = new Win32::ODBC($DSN))){
    print "error connecting to $DSN\n";
    print "error: " . Win32::ODBC::Error() . "\n";
    exit;
}

die qq(SQL failed: ), $db->Error(), qq(\n) if ($db->Sql("SELECT * FROM
+ tbldata"));

while ($db->FetchRow()) {
    my %data = $db->DataHash();
    push @rows, {%data};
}
