点击时如何查询MYSQL?

                    while($request = mysql_fetch_array( $request_db )) {
                    echo "<tr><td style=\"width:33%;padding:1px;\">";
                    echo $request['SongName'];  
                    echo "</td><td style=\"width:33%;\">";
                    echo $request['Artist'];    
                    echo "</td><td style=\"width:33%;\">";
                    echo $request['DedicatedTo'];
                    echo "</td><td style=\"width:33%;\">";
                    echo "UPDATE A ROW's 'Hasplayed' value to '1'.";
                    echo "</td></tr>";  
                }
                echo "</table>";

谢谢!

编辑:如果你想要一个例子,PHPmyAdmin可以这样做。我能用点临时饼干吗?
