更新沙发床中的嵌套数组

Question

[使用下面给出的数据模型：

{
  "snapshots": [
    {
      "createdAt": "2019-03-15T06:31:04.447Z",
      "entries": [
        {
          "balance": 139763,
          "expiresOn": "3019-03-31T23:59Z"

        },
        {
          "balance": 46961,
          "expiresOn": "3019-03-31T23:59Z"

        }
      ]
    }
  ],
  "type": "account"
}

我正在尝试更新快照数组的entries数组中的expiresOn字段，以下是我尝试但不起作用的查询。

UPDATE bucket
SET snapshot.entry.expiresOn = "2020-03-30T23:59Z"
FOR snapshot IN snapshots
  FOR entry IN snapshot.entries
END
WHERE type = "account"

Answer 1

让它起作用，是一个愚蠢的错误。

json模型中的内部数组应该是查询中的外部for循环。

UPDATE bucket
SET snapshot.entry.expiresOn = "2020-03-30T23:59Z"
FOR entry IN snapshot.entries FOR snapshot IN snapshots END
WHERE type = "account"
