Question

简单地说。我需要帮助构建一个FQL多查询请求，该请求将执行以下操作：

从登录用户的好友列表中获取UID，然后
使用这些ID从过去两周内获取所有评论和消息（来自流）
最后，将那些结果与用户名

到目前为止我的查询：

[1] GRAB_UIDs ：

SELECT uid2 FROM friend WHERE uid1 = me()

[2] GRAB_STREAM （错过2周的部分，可能完全错误）：

SELECT type, created_time, post_id, comments, actor_id, target_id, message 
FROM stream 
WHERE filter_key IN 
       (SELECT filter_key FROM stream_filter WHERE uid = me()) 
AND actor_id IN 
       (SELECT uid2 FROM friend WHERE uid1 = me())
)';

[3] GRAB_USRNAMES ：

SELECT uid, name, username, pic_square, current_location, profile_url 
FROM user WHERE uid IN 
       (SELECT uid2 FROM friend WHERE uid1 = me())

我真的可以使用大师来提出这些要求，我非常感谢你的帮助。

Answer 1

{
    "query1":"SELECT uid2 FROM friend WHERE uid1 = me()",
    "query2":"SELECT type, created_time, post_id, comments, actor_id, target_id, message FROM stream WHERE filter_key IN (SELECT filter_key FROM stream_filter WHERE uid = me()) AND actor_id IN (SELECT uid2 FROM #query1)",
    "query3":"SELECT uid, name, username, pic_square, current_location, profile_url FROM user WHERE uid IN (SELECT uid2 FROM #query1)"
}
