while迴圈中的query如何簡化?

我在這裡貼完整的語法 煩請各位mysql大師鑑定

$gettimeline = mysql_query("SELECT * FROM `timeline`LEFT JOIN `users_profile` USING (id)ORDER BY `addtime_timeline`  DESC");

以上是找timeline資料表並以addtime_timeline排列

while ($row=mysql_fetch_array($gettimeline)){ 印出timeline的欄位資料}

以上是印出timeline資料的迴圈

在迴圈中我會加入query 如下

while ($row=mysql_fetch_array($gettimeline)){ $GETthumb1 = mysql_query("SELECT * FROM `timeline_thumb`WHERE `id` = '".$_SESSION['userid']."'AND `by_timeline_id` = '".$row['timeline_id']."'AND `thumb_type` = '1'");$pub_GETthumb1 = mysql_query("SELECT * FROM `timeline_thumb`WHERE `by_timeline_id` = '".$row['timeline_id']."'AND `thumb_type` = '1'");$pub_GETinfo = mysql_query("SELECT * FROM `timeline_thumb`JOIN `users_profile` USING (id)WHERE  `by_timeline_id` = '".$row['timeline_id']."'ORDER BY `addtime_thumb` DESC");$get_comment = mysql_query("SELECT * FROM `timeline_comment`JOIN `users_profile` USING (id)WHERE `re_timeline_id` = '".$row['timeline_id']."' ORDER BY `addtime_comment` DESC ");$get_comment_num = mysql_query("SELECT * FROM `timeline_comment`WHERE `re_timeline_id` = '".$row['timeline_id']."'");}

GETthumb1是找timeline_thumb資料表中與timeline(timeline_id)相符的id(by_timeline_id)有幾筆(抓出用戶自身有幾筆)。
pub_GETthumb1則是總共有幾筆。
pub_GETinfo是抓出用戶的資料與users_profile (id)對應。
get_comment是抓出timeline_comment資料表中與timeline(timeline_id)相符的id(re_timeline_id)有幾筆並抓出用戶的資料與users_profile (id)對應。
get_comment_num是抓出總共有幾筆。

有將mysql查詢簡化的空間嗎?........
