Update jsonb object in postgres - sql

Question

One of my column is jsonb and have value in the format. The value of a single row of column is below.
{
"835": {
"cost": 0,
"name": "FACEBOOK_FB1_6JAN2020",
"email": "test.user#silverpush.co",
"views": 0,
"clicks": 0,
"impressions": 0,
"campaign_state": "paused",
"processed":"in_progress",
"modes":["obj1","obj2"]
},
"876": {
"cost": 0,
"name": "MARVEL_BLACK_WIDOW_4DEC2019",
"email": "test.user#silverpush.co",
"views": 0,
"clicks": 0,
"impressions": 0,
"campaign_state": "paused",
"processed":"in_progress",
"modes":["obj1","obj2"]
}
}
I want to update campaign_info(column name) column's the inner key "processed" and "models" of the campaign_id is "876".
I have tried this query:
update safe_vid_info
set campaign_info -> '835' --> 'processed'='completed'
where cid = 'kiywgh';
But it didn't work.
Any help is appreciated. Thanks.

Answer 1

Is this what you want?
jsonb_set(campaign_info, '{876,processed}', '"completed"')
This updates the value at path "876" > "processed" with value 'completed'.
In your update query:
update safe_vid_info
set campaign_info = jsonb_set(campaign_info, '{876,processed}', '"completed"')
where cid = 'kiywgh';
