I need to generate XML from SQL Server that the end result looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<kmsg xmlns='http://xml.aaa.net/K809' xmlns:env='http://xml.aaa.net/K809/k8msgEnvelope' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'  xsi:schemaLocation='http://xml.aaa.net/K809 k8Order.xsd'>
    <header>
        <env:envelope>
            <env:source branch='2172' endpoint='' machine='0' password=''/>
            <env:destination branch='2172' endpoint='050107' machine='0'/>
            <env:payload>ORDERRESPONSE</env:payload>
            <env:cfcompany>01</env:cfcompany>
            <env:service>ILDLIVE</env:service>
        </env:envelope>
    </header>
    <body>
        <PurchaseOrder xmlns='urn:schemas-basda-org:2000:purchaseOrder:xdr:3.01'>
            <OrderReferences>
                <CrossReference>ABC 1234567</CrossReference>
            </OrderReferences>
        <Extensions xmlns='http://xml.aaa.net/k8msg/k8OrderExtensions'>
                <Direct>FALSE</Direct>
            </Extensions>
            <Supplier>
                <SupplierReferences>
                    <BuyersCodeForSupplier>050107</BuyersCodeForSupplier>
                </SupplierReferences>
            </Supplier>
            <Delivery>
                <PreferredDate>2022-12-24</PreferredDate>
                <SpecialInstructions>Please contact store buyer to confirm quantities and prices, all orders and prices will be final after acceptance of order</SpecialInstructions>
            </Delivery>
            <OrderLine Action='Add' TypeCode='New' TypeDescription='New Item'>
                <Product>
                    <SuppliersProductCode>1000486</SuppliersProductCode>
                    <BuyersProductCode>1000486</BuyersProductCode>
                </Product>
                <Quantity UOMCode='EA' UOMDescription='Each'>
                    <Amount>10</Amount>
                </Quantity>
                <Delivery>
                    <PreferredDate>2022-12-24</PreferredDate>
                </Delivery>
            </OrderLine>
        </PurchaseOrder>
    </body>
</kmsg>

The basic layout has been done but I'm facing trouble with 2 items:

  1. The namespaces at the top. I'm generating the namespaces but it generates out of sync in order of creation and I'm also getting &quot characters. I suspect a characterset mismatch or something similar. How do I get the namespaces to view in the exact order of the document?
  2. How do I add namespaces in the middle of the document? The PurchaseOrder and Extentions tags both have namespaces within them. Can these also be declared at the top of the query, or do I need to add them as static values in SQL?

Here is the code I have currently:

WITH XMLNAMESPACES (
'xsi="http://xml.aaa.net/K809 k8Order.xsd"' AS schemaLocation,
'xsi="http://www.w3.org/2001/XMLSchema-instance"' AS xsi,

'xmlns="http://xml.aaa.net/K809"' AS xmlns1)

SELECT TOP 1

and here is the output I have:

        </Quantity>
      </OrderLine>
    </PurchaseOrder>
  </Body>
</kmsg>

Any help would be appreciated. I'm not used to working with XML in SQL.

I tried using static namespaces in the SQL part but I don't think that is the way to do it

Given some of the errors there are several things you need to keep in mind with XML documents:

  • namespace URIs are case sensitive.
  • element names are case sensitive, so <Body> is a different element than <body> .
  • attribute names case sensitive, so <source Endpoint="..."/> is a different attribute than <source endpoint="..."/> .

WITH XMLNAMESPACES has a particular syntax where 'urn' as prefix defines a namespace URN with a prefix and default 'urn' defines a namespace URN to be used without a prefix, aka. the default namespace.

The following SQL probably isn't correct for your environment but produces XML similar to the output you are looking for - if you update your question to include sample DDL and data this could be tweaked somewhat:

--
-- Setup data...

select 'WHS' as DESTWHS, cast('2022-12-24' as date) as EXPDATEPRD, '1034623' as ITEM, 10 as QEDIT, '050354' as SUPPLIER
into dbo.TableMain; --A

select '2172' as SRCLOC, 'WHS' as SRCWHS
into dbo.Table1; --B

select '01' as FREEATTR3, '2172' as [LOCATION]
into dbo.Table2; --C

select 'KHN4.200CX' as ExternalItemMasterID, '1034623' as ItemCode
into dbo.Table3; --D

select '1034623' as ItemCode, 'Unit of Buy' as Measurement, 'EA' as VolumetricValue
into dbo.Table4; --E

select '1034623' as ItemCode, 'Each' as UnitOfMeasureDesc
into dbo.Table5; --F
