我有这个查询,我想更改它以便获取过去3个月(或从现在起90天)的数据。
select * from yahoo.finance.historicaldata where symbol = "YHOO" and startDate = "2009-09-11" and endDate = "2010-03-10"
有没有"回顾" YQL中有哪些功能?
答案 0 :(得分:0)
如果您想使用YQL,我建议您使用YQL开发人员控制台(启用社区表)
以下YQL语句将从年初到昨天获取Yahoo的历史数据:
select * from yahoo.finance.historicaldata where symbol = "YHOO" and startDate = "2016-01-01" and endDate = "2016-03-24"
此URL将生成以下JSON响应:
