我一直在来回走动，但被难住了。我有一个文件，其中包含跨多个对象的多个 JSON 行。

我在下面放了两行。

{
    "mental_health_act_legal_status": 
    [
        {"legal_status_classification": "16", "start_time": "16:32", "expiry_date": "20171014", "expiry_time": "20:28", "start_date": "20170912"},

    "system": {"record_id": "1484925971009999916", "provider_record_id": "RTD           0167983       0000084", "sus_version": "20170927072844117", "spell_id": "1484925971009999916"}
}

如果我使用openjson语法，我可以让它加载我想要的部分到其中一个表，但文件中只加载了一行；但我需要浏览整个文件。

然后我从这里的一篇文章中查看了一个 .fmt 文件，但从到目前为止我可以看出的是 JSON 行都必须进入同一个表。您不能让多个对象进入该行中的多个表，或者它不知道在哪里拆分它们。

我将其导入 SQL 的代码，仅包含两个表，涵盖系统和心理健康法案的法律状态：

DECLARE @JSON NVARCHAR(MAX)

SET @JSON = (SELECT J.*
             FROM OPENROWSET
             (BULK 'C:\Users\report.jsonl', SINGLE_CLOB)
             AS j)

SELECT * FROM OPENJSON (@JSON, '$.system')
    WITH ([SUS_VERSION] VARCHAR (255) '$.sus_verion',
        [SPELL_ID] VARCHAR (255) '$.spell_id',
        [RECORD_ID] VARCHAR (255)'$.record_id',
        [PROVIDER_RECORD_ID] VARCHAR (255) '$.provider_record_id'
    )

SELECT [record_id], [legal_status_classification], [start_date], [start_time], [expiry_date], [expiry_time]
FROM OPENROWSET (BULK 'C:\Users\report.jsonl', SINGLE_CLOB) AS j
CROSS APPLY OPENJSON (BulkColumn, '$.mental_health_act_legal_status')
WITH (
    [legal_status_classification] VARCHAR (255),
    [start_time] VARCHAR (255),
    [expiry_date] VARCHAR (255),
    [expiry_time] VARCHAR (255),
    [start_date] VARCHAR (255)
    )
CROSS APPLY OPENJSON (BulkColumn, '$.system')
WITH (
    [record_id] VARCHAR (255)
    )

有没有人能够提供建议或帮助或请看什么路线。

谢谢

我不认为这是“格式良好的 JSON”——如果第一行不应该有逗号吗？它不应该被方括号包围吗？有什么东西生成了这个 JSON 吗？

如果您查看从此处提取的示例：https ://docs.microsoft.com/en-us/sql/t-sql/functions/openjson-transact-sql您可以看到大括号中包含多个订单记录用逗号分隔并用方括号括起来

DECLARE @json NVARCHAR(MAX) = N'[  
  {  
    "Order": {  
      "Number":"SO43659",  
      "Date":"2011-05-31T00:00:00"  
    },  
    "AccountNumber":"AW29825",  
    "Item": {  
      "Price":2024.9940,  
      "Quantity":1  
    }  
  },  
  {  
    "Order": {  
      "Number":"SO43661",  
      "Date":"2011-06-01T00:00:00"  
    },  
    "AccountNumber":"AW73565",  
    "Item": {  
      "Price":2024.9940,  
      "Quantity":3  
    }  
  }
]'  

SELECT *
FROM OPENJSON ( @json )  
WITH (   
              Number   varchar(200)   '$.Order.Number',  
              Date     datetime       '$.Order.Date',  
              Customer varchar(200)   '$.AccountNumber',  
              Quantity int            '$.Item.Quantity',  
              [Order]  nvarchar(MAX)  AS JSON  
 )

您可以将数据推送到不同的表。这不是限制OpenJSON，您只需要使用临时表等来确定如何将其拆分。我意识到这不是一个真正的答案，但如果您有兴趣，我会添加更多细节。

我可以使用这种语法获得多行，但这仅仅是因为我为数组添加了方括号，并在元素之间放置了一个逗号：

DECLARE @JSON VARCHAR(MAX);

SET @JSON = '
