我正在尝试从用户的流中检索所有照片。
SELECT post_id, actor_id, target_id, message, created_time
FROM stream
WHERE filter_key in (SELECT filter_key FROM stream_filter WHERE uid = me()
AND type='newsfeed')
AND type = 247
AND is_hidden = 0
ORDER BY created_time DESC
这只返回 4 个结果,它们是最近的帖子。如果我尝试包含一个 'created_time < 1360993620' 子句,它返回零结果。有什么理由为什么这个查询不会过去很远?
