返回JSON数组中满足条件的所有记录？

Question

我们将 JSON 数据存储在 Azure CosmosDB 容器中，如下所示：

   [
    {
            "WebId": "99999996_2_10_125064",
            "SectionId": 1551,
            "rowtype": 4,
            "Fields": [
                    {
                            "FieldId": 8998,
                            "FieldValue": "1002100481",
                            "FieldName": "<p>Project_No</p>8998"
                    },
                    {
                            "FieldId": 9839,
                            "FieldValue": "Customer Name 123",
                            "FieldName": "<p>Customer_Name</p>9839"
                    }
            ]
    },
    {
            "WebId": "99999996_2_10_125064",
            "SectionId": 1552,
            "rowtype": 4,
            "Fields": [
                    {
                            "FieldId": 13362,
                            "FieldValue": "76215_1_9_122345",
                            "FieldName": "<p>LW_WebID</p>13362"
                    },
                    {
                            "FieldId": 10369,
                            "FieldValue": null,
                            "FieldName": "<p>TRM_ID</p>10369"
                    }
            ]
    }
],
[
    {
            "WebId": "99999996_2_10_125070",
            "SectionId": 1551,
            "rowtype": 4,
            "Fields": [
                    {
                            "FieldId": 8998,
                            "FieldValue": "1002100482",
                            "FieldName": "<p>Project_No</p>8998"
                    },
                    {
                            "FieldId": 9839,
                            "FieldValue": "Customer Name 124",
                            "FieldName": "<p>Customer_Name</p>9839"
                    }
            ]
    },
    {
            "WebId": "99999996_2_10_125070",
            "SectionId": 1552,
            "rowtype": 4,
            "Fields": [
                    {
                            "FieldId": 13362,
                            "FieldValue": "94215_1_9_122346",
                            "FieldName": "<p>LW_WebID</p>13362"
                    },
                    {
                            "FieldId": 10369,
                            "FieldValue": null,
                            "FieldName": "<p>TRM_ID</p>10369"
                    }
            ]
    }
]

是否有可能获得所有

WebIDs

，其中

FieldValue

的

Fields.FieldName = <p>LW_WebID</p>13362

是

Fields.FieldValue LIKE '76215_1_9_%'

？从样本数据来看，它应该只获取来自

WebId = '99999996_2_10_125064'

的记录。

目前，我们只能提取具有

Field.FieldId

值

8998, 9839, 13362 and 10369

的所有记录，如下所示。之后，我们在 Power Query 中旋转数据并过滤

LW_WebId

，但是是否可以直接通过本机查询过滤数据？

    SELECT
    c["WebId"]
    , c["SectionId"]
    , c["rowtype"]
    , d["FieldId"]
    , d["FieldName"]
    , d["FieldValue"]
FROM c
JOIN d IN c["Fields"]
WHERE
    c["WebId"] LIKE '99999996_2_10_%'
    d["FieldId"] IN (13362, 8998, 9839)

Answer 1

尝试使用以下查询，它会通过以下相应条件获取带有

WebId = '99999996_2_10_125064'

的记录，如下所示：

SELECT
    c["WebId"]
    , c["SectionId"]
    , c["rowtype"]
    , d["FieldId"]
    , d["FieldName"]
    , d["FieldValue"]
FROM c
JOIN d IN c["Fields"]
WHERE
    c["WebId"] LIKE '99999996_2_10_%'
    AND (
        d["FieldName"] = '<p>LW_WebID</p>13362' AND STARTSWITH(d["FieldValue"], '76215_1_9_')
    )

输出：

[
    {
        "WebId": "99999996_2_10_125064",
        "SectionId": 1552,
        "rowtype": 4,
        "FieldId": 13362,
        "FieldName": "<p>LW_WebID</p>13362",
        "FieldValue": "76215_1_9_122345"
    }
]
