Question

我需要动态地从配置单元表中删除，这就是我要尝试的方式：

   set hivevar:range=select date_sub(date '2019-10-21',19);
   hive> ${hivevar:range};
   OK
   2019-10-02
   Time taken: 0.417 seconds, Fetched: 1 row(s)

但是当我尝试以下

   hive> alter table table_name drop if exists partition (data_date<'${hivevar:range}');

我收到此错误：

   NoViableAltException(340@[319:1: constant : ( ( intervalLiteral )=> intervalLiteral | Number | dateLiteral | timestampLiteral | StringLiteral | stringLiteralSequence | IntegralLiteral | NumberLiteral | charSetStringLiteral | booleanValue | KW_NULL -> TOK_NULL );])

任何想法如何解决这个问题？当我这样尝试时，效果很好：

 alter table table_name drop if exists partition (data_date<'2019-10-02');

但是我想使用如上所示的sub_date。蜂巢是否支持将查询结果存储到变量中？

动态使用sub_date从配置单元表中删除分区
