while循环中的query如何簡化？

$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資料的循环

在循环中我會加入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？........
