创建分区视图时出现 Hive 错误

Question

我有一个“日志”表，它目前按年、月和日进行分区。我想在“日志”表的顶部创建一个分区视图，但遇到了这个错误：

hive> CREATE VIEW log_view PARTITIONED ON (pagename,year,month,day) AS SELECT pagename, year,month,day,uid,properties FROM log; 

FAILED: SemanticException [Error 10093]: Rightmost columns in view output do not match PARTITIONED ON clause

创建分区视图的正确方法是什么？

Answer 1

试试这个..

 CREATE VIEW log_view PARTITIONED ON (pagename,year,month,day) AS SELECT uid,properties,pagename, year,month,day FROM log; 

原因是分区列必须在 select 语句查询的最后。
