配置單元查詢無法正常工作

Question

id                      bigint                  from deserializer   
created_at              string                  from deserializer   
source                  string                  from deserializer   
favorited               boolean                 from deserializer   
retweeted_status        struct<text:string,user:struct<screen_name:string,name:string>,retweet_count:int>   from deserializer   
entities                struct<urls:array<struct<expanded_url:string>>,user_mentions:array<struct<screen_name:string,name:string>>,hashtags:array<struct<text:string>>> from deserializer   
text                    string                  from deserializer   
user                    struct<screen_name:string,name:string,friends_count:int,followers_count:int,statuses_count:int,verified:boolean,utc_offset:int,time_zone:string,location:string>    from deserializer   
in_reply_to_screen_name string                  from deserializer   

。

select  id from election order by election.retweeted_status.retweet_count desc  limit 10

該查詢無法正常工作，錯誤為“ SemanticException [錯誤10002]：行1:53無效的列引用'retweeted_status'”

 select  * from election order by election.retweeted_status.retweet_count desc  limit 10

但是這個查詢正在工作

Answer 1

查詢按以下順序執行

1 FROM子句

2 WHERE子句

3 GROUP BY子句

4 HAVING子句

5 SELECT子句

6 ORDER BY子句

7個極限

當從select子句獲得結果集后執行訂單時，由於尚未在select子句中選擇列，因此orderby子句將無法找到要執行操作的列引用。
