I have the following JSON :
{ "firstName": "John",
"lastName": "Smith",
"isAlive": true,
"age": 27,
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021-3100"
},
"phoneNumbers": [
{
"type": "home",
"number": "212 555-1234"
},
{
"type": "office",
"number": "646 555-4567"
},
{
"type": "mobile",
"number": "123 456-7890"
}
],
"children": [],
"spouse": "Maria"
}
and I am trying to get an array or a table of all the numbers the user have, some users have only 1 number and some have many, is there a way to call all "number" within the json
I am going to try to answer this on my phone, so please forgive the brevity.
SELECT user->>'firstName' as first_name
, user->>'lastName' as last_name
, phone_type
, phone_number
FROM users_tbl
CROSS JOIN LATERAL jsonb_array_elements(user->'phoneNumbers') jarr(num_obj)
CROSS JOIN LATERAL (
SELECT num_obj->>'type' AS phone_type
, num_obj->>'number' AS phone_number
) nums
