从流中获取照片

Question

有没有办法从给定的流查询中获取所有照片？我尝试了以下但它返回一个空集。

SELECT pid, aid, src_big FROM photo WHERE pid IN (SELECT attachment.media.photo.pid FROM #feed)

很难说，因为我看不到你的'#feed'查询，但很可能你错过了一个stream_filter查询。这将为您提供类似以下3个查询的内容。祝你好运！

查询'key'：

SELECT filter_key
  FROM stream_filter
  WHERE uid = me() AND name = 'Photos'

查询'Feed'：

SELECT attachment.media.photo.pid
  FROM stream
  WHERE source_id = {id here} AND filter_key IN (SELECT filter FROM #key)

查询'照片'：

SELECT caption, src_big, modified
    FROM photo
    WHERE pid IN (SELECT pid FROM #feed)
