Hi am doing Android App which takes the Currencies and converts one unit to other unit . am newbie to YQL and I am using YQL(Yahoo Query Language) to get these. When I use (from the YQL console):

select * from yahoo.finance.xchange where pair in ("USDINR") 

I am getting the USD-INR exchange Rate and when I use the query:

select * from yahoo.finance.xchange where pair="USDINR, EURUSD,CADUSD,GBPUSD"

I am getting currency exchanges of USD, INR, EUR, CAD and GBP.

How can I get all the currencies(160 in total), using the Select statement, without hard coding the Currency Codes in YQL? Thanks in advance.
