SQL 查询以获取尚未处理的通知

Question

我有一个 CosmosDb 容器，用于存储通过 SignalR 广播的通知。我已经存储了这 2 个通知：

[
    {
        "createdOn": "2019-12-18T09:48:21.4556896Z",
        "disposed": [
            {
                "disposedBy": "anotherAdmin@mail.com",
                "disposedOn": "2019/11/16T12:00:00"
            }
        ],
        "id": "615b9335-f78f-4a53-9e33-74e1b601d8bd",
        "message": [
            {
                "culture": "en-US",
                "key": "Title",
                "value": "Controller notification!"
            },
            {
                "culture": "en-US",
                "key": "Message",
                "value": "This is an info message received from PushNotifications controller!"
            }
        ],
        "target": "administrators",
        "ttl": 86400,
        "_rid": "iNZhANsdVb0XAQAAAAAAAA==",
        "_self": "dbs/iNZhAA==/colls/iNZhANsdVb0=/docs/iNZhANsdVb0XAQAAAAAAAA==/",
        "_etag": "\"0500558f-0000-0d00-0000-5dfa08d00000\"",
        "_attachments": "attachments/",
        "_ts": 1576667344
    },
    {
        "createdOn": "2019-12-18T09:48:30.4778759Z",
        "disposed": [
            {
                "disposedBy": "admin@mail.com",
                "disposedOn": "2019/11/16T12:00:00"
            },
            {
                "disposedBy": "anotherAdmin@mail.com",
                "disposedOn": "2019/11/16T12:05:03"
            }
        ],
        "id": "287d1ce0-017e-40b5-ab47-9e2222448b33",
        "message": [
            {
                "culture": "en-US",
                "key": "Title",
                "value": "Controller notification!"
            },
            {
                "culture": "en-US",
                "key": "Message",
                "value": "This is an info message received from PushNotifications controller!"
            }
        ],
        "target": "administrators",
        "ttl": 86400,
        "_rid": "iNZhANsdVb0YAQAAAAAAAA==",
        "_self": "dbs/iNZhAA==/colls/iNZhANsdVb0=/docs/iNZhANsdVb0YAQAAAAAAAA==/",
        "_etag": "\"050092b6-0000-0d00-0000-5dfa0c750000\"",
        "_attachments": "attachments/",
        "_ts": 1576668277
    }
]

现在我想创建一个查询来获取 "target" 是 administrators 和 admin@mail.com 处理的不是的所有通知。

我尝试了一些查询，例如：

SELECT value notifications 
FROM notifications JOIN
(SELECT value disposed.disposedBy 
    FROM disposed in notifications.disposed 
    WHERE disposed.disposedBy != "admin@mail.com") 
WHERE notifications.target = "administrators"

和

SELECT value notifications 
FROM notifications JOIN 
(SELECT value disposed.disposedBy 
    FROM disposed IN notifications.disposed 
    WHERE disposed.disposedBy != "admin@mail.com") 
    JOIN (SELECT value notifications 
    WHERE notifications.target = "administrators")

甚至

SELECT value notifications
FROM notifications JOIN 
(SELECT value disposed.disposedBy 
    FROM disposed IN notifications.disposed
    WHERE ARRAY_CONTAINS(disposed.disposedBy, "admin@mail.com"))

但其中 none 给了我预期的结果，即只收到一个通知（ID：615b9335-f78f-4a53-9e33-74e1b601d8bd）。

我如何构建此查询以获取针对某些特定目标但特定用户未处理的通知？

编辑 1： 如果我使用查询

将 disposed 更改为像 disposed: ["user@mail.com", "anotherUser@mail.com"] 这样的字符串数组，我已经想出了如何做到这一点

SELECT value notifications 
FROM notifications 
WHERE NOT Array_Contains(notifications.disposed, "user@mail.com")
AND notifications.target = "administrators"

Answer 1

你差不多明白了。请试试我的 sql:

SELECT value notifications 
FROM notifications
WHERE notifications.target = "administrators"
and not Array_contains(notifications.disposed,{ "disposedBy": "admin@mail.com"},true)

输出：

SQL 查询以获取尚未处理的通知

SQL query to get notifications that haven't been disposed
