Stopping repeated XML Headers

SQL Server version:

Microsoft SQL Server 2016 (SP1-GDR) (KB4458842) - 13.0.4224.16 (X64)   
Copyright (c) Microsoft Corporation  Standard Edition (64-bit) on Windows Server 2016 Standard 6.3 <X64> (Build 14393: ) (Hypervisor)

I have a need to build a nested XML file that has a top tag of monthlydata, then I need a single header present at the top of the file inside monthlydata. Finally, I have repeated fields nested inside the monthlydata but surrounded by the header.

Here is the table design:

CREATE TABLE [dbo].[f_XML_Data]
(
    [SurveyID] [VARCHAR](15) NOT NULL,
    [RecDate] [VARCHAR](15) NOT NULL,
    [DisDate] [VARCHAR](15) NOT NULL,
    [CMS_10] [VARCHAR](50) NULL,
    [CMS_11] [VARCHAR](50) NULL,
    [CMS_23] [VARCHAR](50) NULL,
    [CMS_24] [VARCHAR](50) NULL,
    [CMS_27] [VARCHAR](50) NULL,
    [CMS_30] [VARCHAR](50) NULL,
    [ITADMSRC] [VARCHAR](50) NULL,
    [ITDCGSTA] [VARCHAR](50) NULL,
    [ITDISDAT] [VARCHAR](50) NULL,
    [ITHCAHPS] [VARCHAR](50) NULL,
    [ITSERVIC] [VARCHAR](50) NULL
)

Here is the data:

INSERT INTO dbo.f_XML_Data VALUES ('6561942362','2024-07-10','2024-03-12','Always','Always','8','Definitely yes','Some college','English','1','6','2024-03-12','220090','Storage')

Here is my current code:

SELECT 
    (SELECT 
         'Forward Design' AS [company-name],
         '782837' AS [client-id],
         main.[SurveyID] AS [SurveyID],
         DATEPART(YEAR, [ITDISDAT]) AS [rsp-yr],
         DATEPART(MONTH, [ITDISDAT]) AS [rsp-month]
     FROM 
         dbo.f_XML_Data hdr
     WHERE 
         hdr.[SurveyID] = main.[SurveyID]
     FOR XML PATH('Header'), TYPE),

    (SELECT 
         (SELECT 
              [ITHCAHPS] AS [surveysub-id],
              DATEPART(YEAR, [ITDISDAT]) AS [rsp-yr],
              DATEPART(MONTH, [ITDISDAT]) AS [rsp-month],
              [ITADMSRC] AS [source],  
              [ITSERVIC] AS [principal-reason],

              [CMS_30] AS [language],
              DATEDIFF(DAY, CAST([DisDate] AS DATE), CAST([RecDate] AS DATE)) AS [lag-time],
              '52' AS [supplemental-question-count]
          FROM 
              dbo.f_XML_Data admin
          WHERE 
              admin.[SurveyID] = main.[SurveyID]
          FOR XML PATH(''), ROOT('administration'), TYPE),
         (SELECT
              [CMS_10] AS [cleanliness],
              [CMS_11] AS [quiet],

      FOR XML PATH(''), ROOT('coredata'), TYPE)
FROM 
    dbo.f_XML_Data main
FOR XML PATH(''), ROOT('monthlydata'), TYPE

This is what I get (first two rows only for brevity):

Hope that is what you all are looking for. I really would like to avoid doing string concatenation if possible.

  • sql-server
  • xml
  • t-sql

Please try the following solution.

I had to adjust sample data to allow grouping based on two columns: SurveyID and ITDISDAT that are in the XML’s Header fragment.

SQL
