HTML link utilization with PHP

Hello,

I have a code like this:

/*
$query = "SELECT id, documentPath FROM documentbase WHERE CategoryTitle='Project Org Chart'";

$result = mysql_query($query,$conn) or die('Error, query failed');
$temp = mysql_fetch_row($result);

if($temp[0] != "")
{
?>
<a href="<?php echo $temp[1]; ?>">Project Org Chart</a>
<?php
}
?>

*/

When I keep my pointer on the link it displays an address like below:
file:///D:/Document_Base/StandardDocTest2.doc

But when I click on that to download nothing happens!! I can right click on that link and choose "Save Target As" option but I want the "Save As" dialog box to be appeared with a single left mouse button click. Please advice.
