PostgreSQL jsonb_set multiple elements in array - arrays

Question

I have following jsonb structure in column recipients in a table called mailing:
[
{
"text": "Text1",
"smsId": 1,
"value": "123456",
"status": "Sent"
},
{
"text": "Text1",
"smsId": 2,
"value": "23456",
"status": "Sent"
},
{
"text": "Text1",
"smsId": 3,
"value": "345678",
"status": "Sent"
}]
I need to update one field in multiple elements, so the outcome should look like this:
[
{
"text": "Text1",
"smsId": 1,
"value": "123456",
"status": "Delivered"
},
{
"text": "Text1",
"smsId": 2,
"value": "23456",
"status": "Delivered"
},
{
"text": "Text1",
"smsId": 3,
"value": "345678",
"status": "Delivered"
}]
The most close I got to solution is this:
WITH item AS (SELECT mailing_id, ('{' || INDEX-1 || ',status}')::text[] AS PATH
FROM mailing, jsonb_array_elements(recipients) WITH ORDINALITY arr(recipient, INDEX)
WHERE recipient->>'smsId' = any(array['1', '2', '3']))
UPDATE mailing m
SET recipients = jsonb_set(recipients, item.path, '"Delivered"',FALSE)
FROM item
WHERE m.mailing_id = item.mailing_id;
But this solution updates only first row, and I am not sure if I should somehow loop this or try different approach?

Answer 1

You need to aggregate modified array elements with jsonb_agg():
with new_data as (
select
mailing_id,
jsonb_agg(
case when value->>'smsId' = any('{1,2,3}') then value || '{"status": "Delivered"}'
else value
end) as recipients
from mailing
cross join jsonb_array_elements(recipients)
group by mailing_id
)
update mailing m
set recipients = n.recipients
from new_data n
where m.mailing_id = n.mailing_id;
Test it in db<>fidlle.
