问题
I am using YQL to retrieve Financial Option data. Something like:
select * from yahoo.finance.options where symbol="AAPL" and expiration="2011-07"
However, the above query returns an optionsChain
of data.
Is there a way to retrieve just the record for a specific option symbol, e.g. symbol=AAPL110716C00155000
?
Thanks for your time.

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

I just got all the optionsChain of data by :
select * from yahoo.finance.options where symbol="A" and expiration="2012-10"
And, then just used a JSON Parser to parse the optionsChain's data and got my desired data.
