Converting table with Varchar columns to custom JSON in Snowflake - json

Question

I have a table that has the following data
START_DATE
NAME
ID
01/18/2022
JOHN
10
01/19/2022
ADAM
20
I am trying to convert this to JSON in a custom format like below -
{
"labels":{
"name":"JOHN",
"id":[10]
}
"values":{
"startDate":"01/18/2022"
}
}
PARSE_JSON way of
SELECT parse_json('{"values": {startDate: A.STARTDATE}}')
FROM TABLE_A A;
resulted in error
Error parsing JSON: unknown keyword "A", pos 25
OBJECT_CONSTRUCT results in converting column name as key and column value as value.
Please advise how to have custom field names in JSON conversion in Snowflake.

Answer 1

Renamed objects names as per data given and changed Id to array:
create table test1 values(START_DATE date, NAME string,ID number);
insert into test1(START_DATE, NAME,ID ) values('01/18/2022','JOHN', 10);
insert into test1(START_DATE, NAME,ID ) values('01/19/2022','ADAM', 20);
Select
OBJECT_CONSTRUCT('ID',id::array,'NAME',name) as label_obj,
OBJECT_CONSTRUCT(
'start_date',
START_DATE::string) as start_dt_obj,
object_insert(object_construct('labels', label_obj), 'values', start_dt_obj) as final_json
from
Test1;
