Hive向表中insert数据的问题_error encountered near token

hive insert 动态分区异常(Error encountered near token)与解决

当insert数据到有分区的hive表里时若不明显指定分区会抛出异常

insert overwrite table persons_tmp select * from persons;

FAILED: SemanticException 1:23 Need to specify partition columns because the destination table is partitioned. Error encountered near token 'persons_tmp'

当指定分区后又会有非严格模式异常

insert overwrite table persons_tmp partition(dt,bs)  select * from persons;

FAILED: SemanticException [Error 10096]: Dynamic partition strict mode requires at least one static partition column. To turn this off set hive.exec.dynamic.partition.mode=nonstrict

此时依据错误提示set好非严格模式即可

set hive.
