That is more elegant than the code I wrote to try this out. Thanks for the swift and accurate advice.

I am not sure that I understand the differences in the different pack/unpack codes. What I tried before I got your answer, which also works, was: 

while (@row = $sth->fetchrow_array()) {
        @s = unpack('C*',$row[4]);
        $sid = "0x";
        foreach $s (@s) {
            $sid .= sprintf "%2.2x", $s;
        }
        $row[4] = $sid;
        #print $server,':',$db,':',join(':',@row),"\n";

        $sth_ins->execute($server,$db,@row);
    }

What would the difference be between my code and yours?
