我在這裡貼完整的語法 煩請各位mysql大師鑑定
<code>$gettimeline = mysql_query("SELECT * FROM `timeline`
LEFT JOIN `users_profile` USING (id)
ORDER BY `addtime_timeline` DESC
");
</code>以上是找timeline資料表並以addtime_timeline排列
<code>while ($row=mysql_fetch_array($gettimeline)){
印出timeline的欄位資料
}
</code>以上是印出timeline資料的循環
在循環中我會加入query 如下
<code>while ($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']."'
");
}
</code>GETthumb1是找timeline_thumb資料表中與timeline(timeline_id)相符的id(by_timeline_id)有幾筆(抓出使用者本身有幾筆)。
pub_GETthumb1則是總共有幾筆。
pub_GETinfo是抓出使用者的資料與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)有幾筆並抓出使用者的資料與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？ ........
