正确插入数据：

create table tmp.test_lateral_view_movie_230829(movie string,category array<string>);

insert into tmp.test_lateral_view_movie_230829 select '《战狼3》',array('战争','动作','剧情');
insert into tmp.test_lateral_view_movie_230829 select '《疑犯追踪》',array('悬疑','动作','科幻','剧情');

select * from tmp.test_lateral_view_movie_230829;

原数据

 炸裂：

select 
	movie
	,cate_name 
from tmp.test_lateral_view_movie_230829 
lateral view explode(category) tmp_view as cate_name

结果：

 --------最开始错误的插入数据法-------

 原数据

create table tmp.test_lateral_view_movie_230828(movie string,category array<string>);

select * from tmp.test_lateral_view_movie_230828;

insert into tmp.test_lateral_view_movie_230828 select '《疑犯追踪》',array('悬疑,动作,科幻,剧情');
insert into tmp.test_lateral_view_movie_230828 select '《疑犯追踪2》',array('悬疑,动作,科幻,剧情');
insert into tmp.test_lateral_view_movie_230828 select '《战狼》',array('战争,动作,剧情');
insert into tmp.test_lateral_view_movie_230828 select '《战狼2》',array('战争,动作,剧情');
insert into tmp.test_lateral_view_movie_230828 select '《战狼3》',array('战争,动作,剧情');

 step1：

select 
movie
,category_detail
from tmp.test_lateral_view_movie_230828 lateral view explode(category) tmp as category_detail

step2：

select 
	movie
	,category_detail_name
from 
(
	select 
		movie
		,category_detail
	from tmp.test_lateral_view_movie_230828 lateral view explode(category) tmp as category_detail 
) a
lateral view explode(split(category_detail,',')) tmp as category_detail_name

备注：

select 
	a.movie
	,split(a.category_detail,',') aaa
	,b.category bbb 
from 
(
	select 
		movie
		,category_detail
	from tmp.test_lateral_view_movie_230828 lateral view explode(category) tmp as category_detail 
) a
left join 
(
select * from tmp.test_lateral_view_movie_230828
) b 
on a.movie = b.movie

比原表数据少了 双引号

综上，以上的插入数据是不对的！！！

-----------

注意：

1.array类型数据，建表时怎么插入？

array('悬疑','动作','科幻','剧情')

2.array类型的数据，怎么根据下标获取里面的值？

select 
	movie
	,category[0] 
	,category[1] 
	,category[2] 
from tmp.test_lateral_view_movie_230829
