Answer 1

I Solve by using PHP Script as follows:

//db access
    $dbhost = "localhost";
    $dbuser   = "root";
    $dbpassword = "";
    $database = "dbaname";
    $dbcon = mysql_connect($dbhost, $dbuser, $dbpassword) or die(mysql_error());
    mysql_select_db($database,$dbcon) or die ('>>>'.mysql_errno()."Error1 :".mysql_error());

    //find & Replace 
    $q=mysql_query("SELECT oid,nid FROM tempid") or die(mysql_error());
    while($fetch_com=mysql_fetch_array($q))   {  
        $oid=$fetch_com['oid'];
        $nid=$fetch_com['nid'];     
        mysql_query("UPDATE action SET hotkey=REPLACE(hotkey,',$oid,',',$nid,')");  
    }
