How to extract a JSON value in Hive - sql

Question

I Have a JSON string that is stored in a single cell in the DB corresponding to a parent ID
{"profileState":"ACTIVE","isDefault":"true","joinedOn":"2019-03-24T15:19:52.639Z","profileType":"ADULT","id":"abc","signupDeviceId":"1"}||{"profileState":"ACTIVE","isDefault":"true","joinedOn":"2021-09-05T07:47:00.245Z","imageId":"19","profileType":"KIDS","name":"Kids","id":"efg","signupDeviceId":"1"}
Now I want to use the above JSON to extract the id from this. Let say we have data like
Parent ID | Profile JSON
1 | {profile_json} (see above string)
I want the output to look like this
Parent ID | ID
1 | abc
1 | efg
Now, I've tried a couple of iterations to solve this
First Approach:
select
get_json_object(p.profile, '$$.id') as id,
test.parent_id
from (
select split(
regexp_replace(
regexp_extract(profiles, '^\\[(.+)\\]$$',1),
'\\}\\,\\{', '\\}\\|\\|\\{'),
'\\|\\|') as profile_list,
parent_id ,
from source_table) test
lateral view explode(test.profile_list) p as profile
)
But this is returning the id column as having NULL values. Is there something I'm missing here.
Second Approach:
with profiles as(
select regexp_replace(
regexp_extract(profiles, '^\\[(.+)\\]$$',1),
'\\}\\,\\{', '\\}\\|\\|\\{') as profile_list,
parent_id
from source_table
)
SELECT
get_json_object (t1.profile_list,'$.id')
FROM profiles t1
The second approach is only returning the first id (abc) as per the above JSON string.

I tried to replicate this in apache hive v4.
Data
+----------------------------------------------------+------------------+
| data | parent_id |
+----------------------------------------------------+------------------+
| {"profileState":"ACTIVE","isDefault":"true","joinedOn":"2019-03-24T15:19:52.639Z","profileType":"ADULT","id":"abc","signupDeviceId":"1"}||{"profileState":"ACTIVE","isDefault":"true","joinedOn":"2021-09-05T07:47:00.245Z","imageId":"19","profileType":"KIDS","name":"Kids","id":"efg","signupDeviceId":"1"} | 1.0 |
+----------------------------------------------------+------------------+
Sql
select pid,get_json_object(expl_jid,'$.id') json_id from
(select parent_id pid,split(data,'\\|\\|') jid from tabl1)a
lateral view explode(jid) exp_tab as expl_jid;
+------+----------+
| pid | json_id |
+------+----------+
| 1.0 | abc |
| 1.0 | efg |
+------+----------+

Answer 2

Solve this. Was using a extract $ in the First Approach
select
get_json_object(p.profile, '$.id') as id,
test.parent_id
from (
select split(
regexp_replace(
regexp_extract(profiles, '^\\[(.+)\\]$$',1),
'\\}\\,\\{', '\\}\\|\\|\\{'),
'\\|\\|') as profile_list,
parent_id ,
from source_table) test
lateral view explode(test.profile_list) p as profile
)
