拉链表起始时间转成多行日期

dataphin拉链表起始时间转成多行日期： (ps:dataphin split()怎么都识别不出空格，自闭了。。。替换成字符解决了)

代码语言：javascript复制

select a.*,b.*,dateadd(start_time,pos,'dd')
from (
select
'2021-10-01 00:00:00' as start_time,
'2021-10-03 00:00:00' as end_time
) a
lateral view posexplode(split(replace(space(datediff(end_time,start_time,'dd')),'','a'),'a')) b as pos,val ;
