選項符號「GOOG」在YQL

Question

不工作我試圖檢索使用YQL從雅虎財務數據的選項。非常奇怪的問題是，我可以下載所需的選項信息用於其他符號如AAPL（蘋果）和MSFT（微軟），而不是歌（谷歌）。

這裏是我的查詢和結果。很明顯，我可以檢索AAPL和MSFT的數據，但是GOOG缺失。這不僅發生在yahoo.finance.option_contracts中，而且與所有其他與選項相關的表（包括yahoo.finance.options）發生。我非常確定這不是與查詢限制相關的事情，因爲下面顯示的查詢預計只能檢索到不到10次的GOOG結果。

select * from yahoo.finance.option_contracts where symbol in ('GOOG', 'AAPL', 'MSFT')

     "2016-01" 
    ] 
    } 
    ] 
    } 
} 
} 

總之，每次我試圖檢索GOOG選擇數據的時候，我只得到空的結果與「讀超時」的錯誤。對於其他選項符號，如AAPL和MSFT，我可以得到我想要的。

任何人都知道這是爲什麼？

Answer 1

這必須與谷歌公司交易兩個貼紙（見http://finance.yahoo.com/news/google-trades-under-2-tickers-225300863.html）：GOOG和GOOGL。

YQL不承認GOOG，但會接受新的代碼GOOGL。我懷疑YQL查詢錯誤出乎意料地發現了兩個tickers而不是一個在尋找GOOG時。

如果您請求對雅虎財經一GOOG報價，它的工作原理。
