我正在寻找的是下面的json

      "AgreementId": "100",
      "LoanAccounts": {
        "ProductGroup": "e",
        "Product": "CCOO3",
        "State": "karnataka"
      },
      "FeedbackInfo": {

我尝试使用JSON AUTO和JSON PATH但没有运气。

我已经尝试过以下

    [AGREEMENTID] [nvarchar](200) NULL,
    [ProductGroup] [nvarchar](max) NULL,

select 
    -- Loan account Information
    AGREEMENTID,
    ProductGroup,
    PRODUCT,    
    STATE,  

    -- Feedback Info    
    DispositionCode,
    FeedbackDate,

    -- Payment Info
    [Receipt No]
    [Receipt Date],
    Amount

    from tmpjson
FOR JSON PATH -- FOR JSON AUTO

第二个问题

我可以将结果集放在下面的架构中吗

CREATE TABLE TestJson(AGREEMENTID varchar(200),JsonInfo NVARCHAR(MAX));

WhereAgreementId将在单独的列中，其余信息在JSonInfo.

解决方案

你可以试试下面的一个。我将您的表名与临时表(#tmpjson)一起使用。

SELECT 
    -- Loan account Information
    AGREEMENTID,

    ProductGroup AS 'LoanAccounts.ProductGroup',
    PRODUCT AS 'LoanAccounts.Product',    
    STATE AS 'LoanAccounts.State' , 

    -- Feedback Info    
    DispositionCode AS 'FeedbackInfo.DispositionCode',
    FeedbackDate AS 'FeedbackInfo.FeedbackDate',

    --[Receipt No] AS 'PaymentInfo.ReceiptNo'
    [Receipt Date] AS 'PaymentInfo.ReceiptDate',
    Amount AS 'PaymentInfo.Amount'

FROM #tmpjson FOR JSON PATH, ROOT('AFPInfo')

第二个问题的答案

INSERT TestJson(AGREEMENTID,JsonInfo)
SELECT
  a.AGREEMENTID,

  CAST(
    (
      SELECT 
          -- Loan account Information
          AGREEMENTID,

          ProductGroup AS 'LoanAccounts.ProductGroup',
          PRODUCT AS 'LoanAccounts.Product',    
          STATE AS 'LoanAccounts.State' , 

          -- Feedback Info    
          DispositionCode AS 'FeedbackInfo.DispositionCode',
          FeedbackDate AS 'FeedbackInfo.FeedbackDate',

          --[Receipt No] AS 'PaymentInfo.ReceiptNo'
          [Receipt Date] AS 'PaymentInfo.ReceiptDate',
          Amount AS 'PaymentInfo.Amount'

      FROM tmpjson j
      WHERE j.AGREEMENTID=a.AGREEMENTID
      FOR JSON PATH, ROOT('AFPInfo')
    ) AS nvarchar(MAX)) JsonInfo

FROM
  (
    SELECT DISTINCT AGREEMENTID
    FROM tmpjson
  ) a
