我们有一个 azure 云服务，它记录 Azure Application Insights 的所有异常。我们已设置将所有异常连续导出到 azure 存储表。最重要的是，我们有 Azure 流分析，它从存储 blob 中提取数据并将其推送到 Azure SQL 数据库。现在，问题是我们无法ParsedStack将异常 json 正确转换/格式化为 varchar(max)，以便我们可以将其插入数据库。

这是我们使用的流分析查询 -

SELECT
     CASE 
        WHEN GetArrayLength(A.basicException) > 0
            THEN GetRecordPropertyValue(GetArrayElement(A.basicException, 0), 'assembly')
            ELSE ''
    END AS ExceptionAssembly 
    ,  
     CASE 
        WHEN GetArrayLength(A.basicException) > 0
            THEN GetRecordPropertyValue(GetArrayElement(A.basicException, 0), 'exceptionType')
            ELSE ''
    END AS ExceptionType 
   ,
     CASE 
        WHEN GetArrayLength(A.basicException) > 0
            THEN GetRecordPropertyValue(GetArrayElement(A.basicException, 0), 'parsedstack')
            ELSE ''
    END AS ParsedStack   
      ,A.context.device.id as DeviceId
      ,A.context.device.type as DeviceType
      ,A.context.device.browser as Browser
      ,A.context.device.browserVersion as BrowserVersion
      ,A.context.location.country as Country
      ,A.context.location.province as Province
      ,A.context.location.city as City
    INTO
      myexceptionsoutput
    FROM myexceptionsinput A

SQL 表中的所有值看起来都符合预期，但ParsedStack列的值始终是Microsoft.EventProcessing.SteamR.Sql.ValueArray

添加 Exception 对象 json （完整版很长，所以修剪它更清楚） -

"basicException": [{
        "assembly": "Anonymously Hosted DynamicMethods Assembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null",
        "exceptionType": "System.ServiceModel.CommunicationObjectFaultedException",

        "exceptionGroup": "System.ServiceModel.CommunicationObjectFaultedException at lambda_method",
        "count": 1,
        "outerExceptionMessage": "The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state."
    },
    {
        "parsedStack": [{
            "method": "System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage",
            "assembly": "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089",

            "assembly": "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089",
            "level": 1,

        },
        {

            "assembly": "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089",

        }
    }

目前，无法用 ASA 查询语言将数组序列化为字符串。如果您可以将解析后的堆栈提取到单独的行中，您可以在下面执行

with T1 as
(
select 
  GetArrayElement(iotInput.basicException,0) HighLevelDetails,
  GetRecordPropertyValue (GetArrayElement(iotInput.basicException,1), 'parsedStack') ParsedStack,
  internal.data.id Id
from 
    iotInput 
)

 select
   T1.id,
   T1.HighLevelDetails.assembly,
   T1.HighLevelDetails.exceptionType,
   ParsedStackArray.ArrayValue.method ParsedStackMethod,
   ParsedStackArray.ArrayValue.assembly ParsedStackAssembly,
   ParsedStackArray.ArrayValue.level ParsedStackLevel,
   ParsedStackArray.ArrayValue.line ParsedStackLine
 from 
  T1
 cross apply
   GetArrayElements(T1.ParsedStack) as ParsedStackArray

根据示例事件，将高级详细信息写入表中并将堆栈解析到另一个表中，并将“id”作为公共字段也可能有效。
