使用YQL获取金融期权数据 [英] Get Financial Option Data with YQL

问题描述

我正在使用YQL检索金融期权数据.像这样:

I am using YQL to retrieve Financial Option data. Something like:

select * from yahoo.finance.options where symbol="AAPL" and expiration="2011-07"

但是，上述查询返回数据的optionsChain.

However, the above query returns an optionsChain of data.

有没有一种方法可以只检索特定选项符号的记录，例如symbol=AAPL110716C00155000?

Is there a way to retrieve just the record for a specific option symbol, e.g. symbol=AAPL110716C00155000?

感谢您的时间.

推荐答案

除了远程过滤器"之外，您还可以对从yahoo.finance.options返回的结果集应用所需符号的本地过滤器"( symbol和expiration).

You can apply a "local filter", for your desired symbol, on the result set brought back from yahoo.finance.options in addition to the "remote filters" (symbol and expiration).

select option
from yahoo.finance.options
where symbol = "AAPL" 
  and expiration = "2011-07" 
  and option.symbol = "AAPL110716C00155000" 

有关过滤查询结果的更多信息，请参见 过滤查询结果(WHERE) "页面.

For more info on filtering query results see the Filtering Query Results (WHERE) page in the YQL documentation.
