SQL Server - 将 JSON 字符串解析为 SQL 表格式

Question

我正在尝试将 JSON 字符串转换为 SQL Server 中的表格式。 我需要的元素和值实际上在“GetCustomReportResult”标签中。 但是，当我尝试执行以下查询时收到一条错误消息：

消息 13609，级别 16，状态 4，第 63 行 JSON 文本格式不正确。 在位置 916 处发现了意外字符“T”。

DECLARE @json NVARCHAR(MAX)
SET @json=
'{
   "status":"ok",
   "data":{
      "response":{
         "GetCustomReportResult":{

            },
            "Managers":null,
            "Parameters":{
               "Consent":True,

                     "infoReport"
                  ]
               },
               "SubjectType":"Individual"
            },
            "PaymentIncidentList":null,
            "PolicyRulesCheck":null,
            "ReportInfo":{

            "Shareholders":null,

            "TaxRegistration":null,
            "Utilities":null
         }
      }
   },
   "errormsg":null
}'
SELECT *
FROM OPENJSON(@json);

JSON 字符串实际上存储在 SQL 表中的一列中，如下所示，我正在尝试以表格格式转换标记“GetCustomReportResult”中的元素，其中包含每个“ApplicationID”的列和值。

这是我尝试过但出现错误的方法：

消息 13609，级别 16，状态 2，第 1 行 JSON 文本的格式不正确。 在位置 0 处发现了意外字符“o”。

SELECT 
y.cijreport,
y.ApplicationId,
JSON_VALUE(x.value, '$.CIP') as CIP,
JSON_VALUE(x.value, '$.CIQ') as CIQ
--other fields
FROM table as y
CROSS APPLY OPENJSON (cijreport) as x
where cijreport is not null

如果 true 是文字，那么您缺少引号。

DECLARE @json NVARCHAR(MAX)
SET @json=
'{
   "status":"ok",
   "data":{
      "response":{
         "GetCustomReportResult":{

如果true是布尔表达式，则删除大写的T并将其替换为t

DECLARE @json NVARCHAR(MAX)
SET @json=
'{
   "status":"ok",
   "data":{
      "response":{
         "GetCustomReportResult":{
