Question

我正在尝试将yql用于雅虎财务数据。我检查了YQL控制台上的Show Community Table以查看Yahoo标签下的数据库。
我发布了样本yql：
https://developer.yahoo.com/yql/console/?q=show%20tables&env=store://datatables.org/alltableswithkeys#h=SELECT+*+FROM+yahoo.finance.analystestimate+WHERE+symbol%3D'PRLB'
但是我得到了这个结果：

"results": {
  "results": {
  "symbol": "PRLB"
  }
}

我原本期望从here获取一些格式化数据作为盈利预测，EPS趋势......类似表格也是如此。
我做错了什么？

Answer 1

该表的JS不再工作，即需要修复。

这是部分格式化的......
