如何插入配置单元 table,按从临时 table 读取的日期分区?

How to insert into hive table, partitioned by date reading from temp table?

我有一个 Hive temp table,没有任何具有所需数据的分区。我想 select 这个数据并插入到另一个按日期分区的 table 中。我尝试了以下技术但没有成功。

来源table架构

 CREATE TABLE cls_staging.cls_billing_address_em_tmp
( col1 string,
 col2 string,
col3 string);

目的地table:

CREATE TABLE cls_staging.cls_billing_address_em_tmp
    ( col1 string,
     col2 string,
    col3 string) 
    PARTITIONED BY (
       curr_date string) 
      STORED AS ORC;

插入目标的查询table:

insert overwrite table cls_staging.cls_billing_address_em_tmp partition (record_date)  select col1, col2, col3, FROM_UNIXTIME(UNIX_TIMESTAMP()) from myDB.mytbl;

错误

Dynamic partition strict mode requires at least one static partition column

第二

insert overwrite table cls_staging.cls_billing_address_em_tmp partition (record_date = FROM_UNIXTIME(UNIX_TIMESTAMP()))  select col1, col2, col3 from myDB.mytbl;

错误:

cannot recognize input near 'FROM_UNIXTIME' '(' 'UNIX_TIMESTAMP'

第一次开启动态分区和非严格模式:

set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;

insert overwrite table cls_staging.cls_billing_address_em_tmp partition (record_date)  
select col1, col2, col3, current_timestamp from myDB.mytbl;

2nd:不要用unix_timestamp()这个目的,因为它会产生很多不同的时间戳,使用current_timestamp常量,读这个:
