couchbase - 更新 n1q1 查询 CB 中的子文档映射

Question

这是我在 CB 中的文档，

{
    "users": {
        "11111": "ACTIVE",
        "22222": "ACTIVE",
        "33333": "ACTIVE",
        "44444": "ACTIVE",
        "55555": "ACTIVE",
        "666666": "ACTIVE",
        "777777": "ACTIVE",
        "888888": "ACTIVE"
    }
}

我想将此用户映射的所有键更新为 0 而不是事件的。

预期输出

{
    "users": {
        "11111": 0,
        "22222": 0,
        "33333": 0,
        "44444": 0,
        "55555": 0,
        "666666": 0,
        "777777": 0,
        "888888": 0
    }
}

我试过了

UPDATE bucketname SET x=0 FOR x in bucketname.users END WHERE meta().id='%documentKey%'

Answer 1

UPDATE mybucket AS b
SET b.users = OBJECT n:0 FOR n:v IN b.users END
WHERE ......

构造新对象并设置值

FOR n:v IN b.users END
   iterates each field of b.users (n holds name, v holds value)

OBJECT n:0  
   Construct new object field name from n and value is 0 constant
