嗨, 我有一个包含以下列的配置单元表 partid字符串,表中存储字符串和位置数组,值按此顺序保存
part123, store123, location
[{"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}]
>
我可以在一行中看到arry的值,我也想 以这种方式查看partid,store和location值。 >
+---------+-----+----------+--------+-----------+----------+
partid |store | position | price | card_pos | clicked |
+---------+-----+----------+--------+-----------+----------+
part123|store123| 1 | 124.0 | External | 0 |
part123|store123| 2 | 94.78 | Cbox | 0 |
part123|store123| 3 | 94.77 | External | 0 |
+---------+-----+----------+----------+----------+---------+
> 到目前为止,我只能通过以这种方式使用内联函数来查看数组值。
select inline(location) as (position, price, card_pos, clicked) from table;
>+---------+--------+-----------+----------+
| position | price | card_pos | clicked |
+----------+--------+-----------+----------+
| 1 | 124.0 | External | 0 |
| 2 | 94.78 | Cbox | 0 |
| 3 | 94.77 | External | 0 |

答案 0 :(得分:1)
将mock-rest
与lateral view
结合使用,然后选择其他列。
inline
编辑:如果OP处理select partid,store,t.position,t.price,t.card_pos,t.clicked
from table
lateral view inline(location) t as position, price, card_pos, clicked
列为array
时的情况,请使用null
选项。
lateral view outer
