使用 T-SQL 语法生成复杂的 XML

Question

我正在尝试构建一个返回或多或少复杂的 XML 结构的查询。这是我想要的预期输出：

<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
    <s:Header>
        <a:Action s:mustUnderstand="1">http://tempuri.org/IGeocodeService/HereRouteMatchExtension</a:Action>
        <a:MessageID>urn:uuid: some_messageID</a:MessageID>
        <a:ReplyTo>
            <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
        </a:ReplyTo>
        <a:To s:mustUnderstand="1">ServiceURL</a:To>
    </s:Header>
    <s:Body>
                 <HereRouteMatchExtension xmlns="http://tempuri.org/">
                       <vehicleTrace xmlns:b="http://schemas.datacontract.org/2004/07/FMCommonTypes.WCF" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
                                  <s:Latitude>2</s:Latitude>
                                  <s:Longitude>2</s:Longitude>
                                  <s:PositionGuid>577AF773-C7A8-4D65-82DA-37A15CC7611D</s:PositionGuid>
                       </vehicleTrace>
                 </HereRouteMatchExtension>
    </s:Body>
</s:Envelope>

我正在使用以下代码：

CREATE TABLE #test
(
    Latitude INT,
    Longitude INT, 
    PositionGuid UNIQUEIDENTIFIER
)

INSERT INTO #test VALUES (1,1,NEWID())
INSERT INTO #test VALUES (2,2,NEWID())



WITH XMLNAMESPACES ('http://www.w3.org/2003/05/soap-envelope' AS s, 'http://www.w3.org/2005/08/addressing' AS a)
SELECT
( SELECT '1' AS  [a:Action/@mustUnderstand], 
 'http://tempuri.org/IGeocodeService/HereRouteMatchExtension' AS [a:Action]
  FOR XML PATH (''), TYPE
),
'urn:uuid: some_messageID' AS 'a:MessageID',
( SELECT  'http://www.w3.org/2005/08/addressing/anonymous' AS [a:Address]
  FOR XML PATH ('a:ReplyTo'), TYPE
),
( SELECT '1' AS  [a:To/@mustUnderstand], 
 'ServiceURL' AS [a:To]
  FOR XML PATH (''), TYPE
),
( SELECT '1' AS  [a:Action/@mustUnderstand]
FOR XML PATH (''), TYPE

),
(SELECT Latitude AS 's:Latitude',
       Longitude      AS 's:Longitude', 
       PositionGuid     AS 's:PositionGuid'
FROM #test
FOR XML PATH ('s:Body'),  TYPE
)

FOR XML RAW ('s:Header'), ELEMENTS, ROOT('s:Envelope')

我生成的代码有2个问题：

1) 参考网址在每个小节中，我希望只有一次；

2) 正文标签在标题内，它应该直接在它之后...

我怎样才能做到这一点？这是我得到的结果：

<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
  <s:Header>
    <a:Action xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope" mustUnderstand="1">http://tempuri.org/IGeocodeService/HereRouteMatchExtension</a:Action>
    <a:MessageID>urn:uuid: some_messageID</a:MessageID>
    <a:ReplyTo xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
      <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
    </a:ReplyTo>
    <a:To xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope" mustUnderstand="1">ServiceURL</a:To>
    <a:Action xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope" mustUnderstand="1" />
    <s:Body xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
      <s:Latitude>1</s:Latitude>
      <s:Longitude>1</s:Longitude>
      <s:PositionGuid>34BD8E91-8567-4D58-A18E-61C3FBBF5C8F</s:PositionGuid>
    </s:Body>
  </s:Header>
</s:Envelope>

Answer 1

试试看

DECLARE  @test TABLE
(
    Latitude INT,
    Longitude INT, 
    PositionGuid UNIQUEIDENTIFIER
)

INSERT INTO @test VALUES (1,1,NEWID());
INSERT INTO @test VALUES (2,2,NEWID());

    WITH XMLNAMESPACES ('http://www.w3.org/2003/05/soap-envelope' AS s, 'http://www.w3.org/2005/08/addressing' AS a)
    SELECT
        1 AS [s:Envelope/s:Header/a:Action/@s:mustUnderstand],
        'http://tempuri.org/IGeocodeService/HereRouteMatchExtension' AS [s:Envelope/s:Header/a:Action],
        'urn:uuid: some_messageID' AS [s:Envelope/s:Header/a:MessageID],
        'http://www.w3.org/2005/08/addressing/anonymous' [s:Envelope/s:Header/a:ReplyTo/a:Address],
        1  as [s:Envelope/s:Header/To/@s:mustUnderstand],
        'ServiceURL' as  [s:Envelope/s:Header/To],
        Latitude as [s:Envelope/s:Body/s:Latitude],
        Longitude as  [s:Envelope/s:Body/s:Longitude],
        PositionGuid as  [s:Envelope/s:Body/s:PositionGuid]
        FROM @test
        FOR XML PATH('')

这样您就可以为@table 的每一行生成两个Envelope 元素。

编辑：

在使用 FOR XML PATH 的子查询中使用 TYPE 生成时，我找不到从子元素中删除额外命名空间的方法。

我想出了这个不能完全满足我的解决方案：

DECLARE  @test TABLE
(
    Latitude INT,
    Longitude INT, 
    PositionGuid UNIQUEIDENTIFIER,
    x xml
)



DECLARE @x xml = 
'<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
    <s:Header>
        <a:Action s:mustUnderstand="1">http://tempuri.org/IGeocodeService/HereRouteMatchExtension</a:Action>
        <a:MessageID>urn:uuid: some_messageID</a:MessageID>
        <a:ReplyTo>
            <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
        </a:ReplyTo>
        <a:To s:mustUnderstand="1">ServiceURL</a:To>
    </s:Header>
    <s:Body>
                <HereRouteMatchExtension xmlns="http://tempuri.org/">
                       <vehicleTrace xmlns:b="http://schemas.datacontract.org/2004/07/FMCommonTypes.WCF" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
                                  <s:Latitude>2</s:Latitude>
                                  <s:Longitude>2</s:Longitude>
                                  <s:PositionGuid>577AF773-C7A8-4D65-82DA-37A15CC7611D</s:PositionGuid>
                       </vehicleTrace>
                 </HereRouteMatchExtension>
    </s:Body>
</s:Envelope>'

INSERT INTO @test VALUES (10,10,NEWID(),@x);
INSERT INTO @test VALUES (20,20,NEWID(),@x);


UPDATE @test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element  namespace "http://tempuri.org/";
replace value of (/s:Envelope/s:Body/HereRouteMatchExtension/vehicleTrace/s:Latitude/text())[1] with sql:column("Latitude")')
UPDATE @test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element  namespace "http://tempuri.org/";
replace value of (/s:Envelope/s:Body/HereRouteMatchExtension/vehicleTrace/s:Longitude/text())[1] with sql:column("Longitude")')
UPDATE @test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element  namespace "http://tempuri.org/";
replace value of (/s:Envelope/s:Body/HereRouteMatchExtension/vehicleTrace/s:PositionGuid/text())[1] with sql:column("PositionGuid")')


SELECT * FROM @test

全部插入：

DECLARE  @test TABLE
(
    Latitude INT,
    Longitude INT, 
    PositionGuid UNIQUEIDENTIFIER,
    x xml
)



DECLARE @x xml = 
'<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">

            <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
        </a:ReplyTo>
        <a:To s:mustUnderstand="1">ServiceURL</a:To>
    </s:Header>
    <s:Body>
                <HereRouteMatchExtension xmlns="http://tempuri.org/">
                 </HereRouteMatchExtension>
    </s:Body>
</s:Envelope>'

INSERT INTO @test VALUES (10,10,NEWID(),@x);
INSERT INTO @test VALUES (20,20,NEWID(),@x);

UPDATE @test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element  namespace "http://tempuri.org/";
insert  <vehicleTrace xmlns:b="http://schemas.datacontract.org/2004/07/FMCommonTypes.WCF" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><s:Latitude>{sql:column("Latitude")}</s:Latitude>
        <s:Longitude>{sql:column("Longitude")}</s:Longitude>
        <s:PositionGuid>{sql:column("PositionGuid")}</s:PositionGuid></vehicleTrace> into (/s:Envelope/s:Body/HereRouteMatchExtension)[1]')


SELECT * FROM @test
