之前有人可以使用该功能，但我几乎尝试了每种组合以查看其是否有效。

这是我要与内联一起使用的结构数组

[{"position":1,"price":124.0,"card_pos":"External","clicked":0},
 {"position":2,"price":94.78,"card_pos":"Cbox","clicked":0},
 {"position":3,"price":94.77,"card_pos":"External","clicked":0}] 

这很好用：

[{"position":1,"price":124.0,"card_pos":"External","clicked":0},
 {"position":2,"price":94.78,"card_pos":"Cbox","clicked":0},
 {"position":3,"price":94.77,"card_pos":"External","clicked":0}] 

我可以使内联函数正常工作有点烦人。Hive Wiki上的文档对于如何正确使用此功能非常含糊。

我们有Hive 0.10（CDH4.6），内联函数绝对是我们发行版的一部分。

如果有人作为具体用法的例子，请告诉我

我尝试了几种不同的语法

select iq.*, iq.card.position as position, 
iq.card.price as price,iq.card.card_pos as card_pos, 
iq.card.clicked as clicked 
from
(
  select *
  from 
  hsim.im_metasearch
  LATERAL VIEW explode(cards) card as card
) iq

我也曾尝试将其放入选择中，但没有成功，谢谢
