在 postgres 中更新 jsonb 对象

Question

我的专栏之一是 jsonb 并且具有格式价值。单行列的值如下。

{
    "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"]
    }
}

我想更新campaign_info（列名）列的内部键“已处理”和“模型”的campaign_id 是“876”。

我试过这个查询：

update safe_vid_info 
set campaign_info -> '835' --> 'processed'='completed' 
where cid = 'kiywgh'; 

但它没有用。

任何帮助表示赞赏。谢谢。

Answer 1

这是你想要的吗？

jsonb_set(campaign_info, '{876,processed}', '"completed"')

这会使用 value 更新 path 处"876" > "processed"的值'completed'。

在您的更新查询中：

update safe_vid_info 
set campaign_info = jsonb_set(campaign_info, '{876,processed}', '"completed"')
where cid = 'kiywgh';
