问题
I'm new to YQL. Perhaps this is very trivial, but I couldn't quite figure this out. I know, for instance, how to query current stock data from Yahoo/YQL using the YQL console:
http://developer.yahoo.com/yql/console/
with the query string:
select * from yahoo.finance.quotes where symbol in ("YHOO","AAPL","GOOG","MSFT")
However, what if I want, say, the same data from yesterday, or a week ago? I tried things such as
select * from yahoo.finance.quotes where symbol in ("YHOO","AAPL","GOOG","MSFT") and date=20120913
But it doesn't appear to work.
Any suggestion is appreciated!
回答1:
You're using the wrong table.
select * from yahoo.finance.historicaldata where symbol = "YHOO" and startDate = "2009-09-11" and endDate = "2010-03-10"
Alternatively, you could use stockretriever.py for this. In the source code, you can find a workaround for historical data.

The table is correct. You need to append the store parameter in your query string. Here is the sample string.
http://query.yahooapis.com/v1/public/yql?q=select * from yahoo.finance.historicaldata where symbol = "YHOO" and startDate = "2014-02-11" and endDate = "2014-02-18"&diagnostics=true&env=store://datatables.org/alltableswithkeys
Hope it helps you.

yahoo.finance.historicaldata is working, but you have to use startDate and endDate:
select * from yahoo.finance.historicaldata where symbol in ("YHOO","AAPL","GOOG","MSFT") and startDate = "2012-09-13" and endDate = "2012-09-13"
