這FQL試圖爲我的朋友擷取相片FQL:選擇朋友的照片
[1]
{"query1":"SELECT owner, object_id, src_big FROM photo
WHERE owner IN (SELECT uid2 FROM friend WHERE uid1=me())"}
提供思考了幾秒鐘後,這個錯誤響應...
{"error_code":1,"error_msg":"An unknown error occurred"}
但這個查詢爲我的朋友抓取相冊將工作並返回相冊信息的JSON對象
[2]
{"query1":"SELECT aid, owner, name FROM album
WHERE owner IN (SELECT uid2 FROM friend WHERE uid1=me())"}
爲什麼[2]可以工作,但不是[1]?
爲什麼2級查詢的作品,但1子查詢不使用多查詢? –
