ช่วยด้วยครับ ใช่คำสั่ง update ไม่ได้ รบกวนท่านผู้รู้ดูให้ด้วยครับ

<? include('config.inc.php');
$sql_show = "select * from Datametertotal where Name = 'DBP - F1'";
$result_show = mysql_query($sql_show) or die(mysql_error());
while($row_show=mysql_fetch_array($result_show))
{
?>
<? include('config.inc.php');
$id = $row_show['ID'];
$n = 'F1-DBP';
$strSQL = "UPDATE Datametertotal SET";
$strSQL .="Name = $n";
$strSQL .="where ID = $id";
$objQuery = mysql_query($strSQL);
if($objQuery)
{
	echo "Save Done.";
}
else
{
	echo "Error Save [".$strSQL."]";
}
?>
<table width="200" border="1">
  <tr>
    <td><?=$row_show['Name']?></td>
    <td><?=$row_show['ID']?></td>
    <td>&nbsp;</td>
  </tr>
</table>
<?
}
?>
