select id from election order by election.retweeted_status.retweet_count desc limit 10
此查询无效 错误是“SemanticException [错误10002]:行1:53无效的列引用'retweeted_status'”
select * from election order by election.retweeted_status.retweet_count desc limit 10
但是这个查询正在运行
答案 0 :(得分:0)
查询按以下顺序执行
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限制
当我们从select子句获得结果集后执行顺序,因为你没有选择select子句中的列orderby子句将无法找到列引用来执行操作。
