Question

我正在使用SQL Express Edition 2016

这是我的查询。它返回空值。

Declare @JSON varchar(max)
SELECT @JSON = BulkColumn
FROM OPENROWSET (BULK 'F:\JKPM\18Aug2018\Mod1.json', SINGLE_CLOB) as j

SELECT * FROM OPENJSON (@JSON) 
WITH(transactionId nvarchar(50))

我的JSON是：

{
    "data": {
        "deviceTransactions": [{
            "transactionId": "3f147089-ff52-5552-a29b-cd32a7e2ba97",
            "organizationId": "9023179c-7888-4c5e-a831-28259b8a8872",

                "error": {
                    "errorMessage": "Failed to start polling status of the Queue",
                    "stage": "MANAGE_PUSH",
                    "errorCode": "ERR021001"
                },
                "jcigId": "4rtr5aa6a2-71b5-455f-8890-7e2aa398b757"
            },
            "cancelledBy": ""
        }],
        "libraryTransactions": []
    },
    "success": true,
    "statusCode": 200
}

Answer 1

transactionId是deviceTransactions的一部分，也是一个数组。这是在这种情况下如何使用openjson的示例：

OPENJSON提供空值
