如何解决SQL Server 将 JSON 对象解析为行
在此先感谢您的帮助。这要死我了！ :-)
我有一个 JSON 字符串，其中嵌套了一个对象集合，我需要从中获取标准 SQL 结果集。这是我正在使用的 JSON 的示例字符串：

可以将此字符串粘贴到在线 JSON 解析器中以更轻松地可视化层次结构（如 http://json.parser.online.fr/）。
我想要做的是使用 SQL Server OPENJSON 函数来获取此 JSON 字符串中 3 个示例声明的结果集。声明嵌套在 $.Loop2000.Loop2100 中，我试图得到的结果是：
Patient Account Number ClaimStatusCode TotalClaimChargeAmount
------------------------------------------------------------------------
Patient Account Number 1 34.25
Patient Account Number 2 34.00
Patient Account Number 3 34.00
我似乎无法在 OPENJSON 函数中找到正确的路径以将其转换为具有 3 行的结果集。我正在尝试使用类似的东西：
SELECT * FROM OPENJSON(@sJSON,N'$.Loop2000.Loop2100')
WITH (
PatientControlNumber_01 nvarchar(100) '$.CLP_ClaimPaymentInformation.PatientControlNumber_01'
)
任何帮助将不胜感激。
解决方法
您可以使用的一种方法是一些嵌套的 OPNEJSON 调用：
SELECT CPI.*
FROM OPENJSON(@JSON,N'$.Loop2000')
WITH (Loop2100 nvarchar(MAX) AS JSON) L2000
CROSS APPLY OPENJSON(L2000.Loop2100)
WITH(CLP_ClaimPaymentInformation nvarchar(MAX) AS JSON) L2100
CROSS APPLY OPENJSON(L2100.CLP_ClaimPaymentInformation)
WITH (PatientControlNumber varchar(100) '$.PatientControlNumber_01',ClaimStatusCode int '$.ClaimStatusCode_02',TotalClaimChargeAmount decimal(12,2) '$.TotalClaimChargeAmount_03') CPI;
