谷歌的BigQuery - 在github上時間軸表

Question

奇怪查詢錯誤我已經在谷歌大查詢服務執行一個查詢，與誤解的錯誤

Error: Field 'evt.repository_name' not found in table 'evt'.

，因爲該領域的表中存在指出錯誤的位置。任何人都可以幫我解決這個問題？

查詢：

select nname 
    from (
     select evt.repository_name nname, count(evt.payload_issue_id) issues_count 
     from [publicdata:samples.github_timeline] evt 
      where upper(repository_language)='JAVA' 
      AND evt.repository_name in (
       select name from (

        select evt1.repository_name name, count(evt1.payload_commit_id) commits_count 
        from [publicdata:samples.github_timeline] evt1 
        where upper(repository_language)='JAVA' 
        group by name 
        order by commits_count desc 
        limit 20 
           ) 
      as foo2)  
    group by nname 
    order by issues_count desc 
    limit 20) as foo

這一個工程：

select nname 
    from (
     select repository_name as nname, count(payload_issue_id) as issues_count 
     from [publicdata:samples.github_timeline] as evt 
      where upper(repository_language)='JAVA' 
      AND repository_name in (
       select name from (

        select evt1.repository_name name, count(evt1.payload_commit_id) commits_count 
        from [publicdata:samples.github_timeline] evt1 
        where upper(repository_language)='JAVA' 
        group by name 
        order by commits_count desc 
        limit 20 
           ) 
      as foo2)  
    group by nname 
    order by issues_count desc 
    limit 20) as foo
