海外の株式マーケットのTickerシンボル一覧が欲しく探してみたところ  
YQLで取得が可能だという情報を見つけたのですが、試してみても検索結果が0になってしまいます。

具体的には

```

    select * from yahoo.finance.industry where id in (select industry.id from yahoo.finance.sectors)
    
```

の結果が

```

    {
     "query": {
      "count": 0,
      "created": "2015-05-03T07:01:26Z",
      "lang": "en-US",
      "diagnostics": {
       "url": [
        {
         "execution-start-time": "1",
         "execution-stop-time": "5",
         "execution-time": "4",
         "content": "http://www.datatables.org/yahoo/finance/yahoo.finance.industry.xml"
        },
        {
         "execution-start-time": "6",
         "execution-stop-time": "8",
         "execution-time": "2",
         "content": "http://www.datatables.org/yahoo/finance/yahoo.finance.sectors.xml"
        },
        {
         "execution-start-time": "15",
         "execution-stop-time": "35",
         "execution-time": "20",
         "content": "http://biz.yahoo.com/ic/ind_index.html"
        },
        {
         "execution-start-time": "15",
         "execution-stop-time": "35",
         "execution-time": "20",
         "content": "http://biz.yahoo.com/ic/ind_index.html"
        }
       ],
       "publiclyCallable": "true",
       "query": {
        "execution-start-time": "12",
        "execution-stop-time": "51",
        "execution-time": "39",
        "params": "{url=[http://biz.yahoo.com/ic/ind_index.html]}",
        "content": "select * from html where url=@url and xpath='//td[@width=\"50%\"]/table/tr/td'"
       },
       "javascript": {
        "execution-start-time": "11",
        "execution-stop-time": "51",
        "execution-time": "40",
        "instructions-used": "12000",
        "table-name": "yahoo.finance.sectors"
       },
       "user-time": "52",
       "service-time": "38",
       "build-version": "0.2.450"
      },
      "results": null
     }
    }
    
```

になってしまいます。

コードの実行は[こちら](https://developer.yahoo.com/yql/console/?q=show%20tables&env=store://datatables.org/alltableswithkeys#h=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20\(select%20industry.id%20from%20yahoo.finance.sectors\))で、また元のコードは[本家Stackoverflowの回答](https://stackoverflow.com/questions/5246843/how-
to-get-a-complete-list-of-ticker-symbols-from-yahoo-finance)から使わせてもらっています。

すでにこのコードは使えなくなっているのでしょうか？  
それとも何か実行の方法が間違っていますか？
