我有两张Hive桌。
源表有以下列:
correspondence_id | decimal(22,0) | |
| template_id | decimal(18,0) | |
| language_cd | varchar(6) | |
| delivery_channel_cd | varchar(20) | |
| job_id | decimal(18,0) | |
| correspondence_content | string | |
| create_user_id | varchar(40) | |
| create_ts | timestamp | |
| last_updt_user_id | varchar(40) | |
| last_updt_ts | timestamp | |
| data_src_id | decimal(18,0) | |
| src_app_resource_cd | varchar(50)
目标包含以下列:
correspondence_id | decimal(22,0) | |
| template_id | decimal(18,0) | |
| template_cd | varchar(20) | |
| template_type_cd | varchar(40) | |
| category_cd | varchar(20) | |
| language_cd | varchar(6) | |
| delivery_channel_cd | varchar(20) | |
| job_id | decimal(18,0) | |
| correspondence_content | string | |
| create_user_id | varchar(40) | |
| create_ts | timestamp | |
| last_updt_user_id | varchar(40) | |
| last_updt_ts | timestamp | |
| data_src_id | decimal(18,0) | |
| src_app_resource_cd | varchar(50) | |
| part_create_year_num | int | |
| part_create_month_num | int | |
| | NULL | NULL |
| # Partition Information | NULL | NULL |
| # col_name | data_type | comment |
| | NULL | NULL |
| part_create_year_num | int | |
| part_create_month_num | int
im使用以下查询传输数据:
FROM source_table cc insert overwrite table
destination_table partition
(part_create_year_num=2016, part_create_month_num=9 )
select cc.correspondence_id, cc.template_id, cc.language_cd, cc.delivery_channel_cd, cc.job_id,
cc.correspondence_content, cc.create_user_id, cc.create_ts, cc.last_updt_user_id, cc.last_updt_ts,
cc.data_src_id, cc.src_app_resource_cd
但是当我运行这个查询时,我得到以下错误
rror: Error while compiling statement: FAILED: SemanticException [Error 10044]: Line 1:79 Cannot insert into target table because column number/types are different '9': Table insclause-0 has 15 columns, but query has 12 columns. (state=42000,code=10044)
org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: FAILED: SemanticException [Error 10044]: Line 1:79 Cannot insert into target table because column number/types are different '9': Table insclause-0 has 15 columns, but query has 12 columns.
很明显,源表和目标表是不同的,但是如何才能使这个查询工作,我尝试过输入占位符值,但也没有工作。

按热度按时间vsaztqbk1#
似乎目标表有五个额外的列
标准列:1模板| varchar(20)| 2模板|类型| varchar(40)| 3类别| cd | varchar(20)||
分区列4。创建第5年。零件|创建|月份|整数
查询应为
