Question

收到xml文件，我从中获得发货人的框架。然后我生成一个答案xml，我想在源xml中使用一些块。这就是为什么我试图插入＆＃34;发货人＆＃34;变量，它是另一个xml实例中的xml实例。没有错误，但是，它没有插入值... 什么可能是错的？

DECLARE @source_vsd xml,
        @output_vsd xml

Answer 1

显然，更新XML变量存在一些问题，因为只要将值放入表中（并将名称空间移动到with namespaces()部分），一切就会开始按原样运行：

insert into @t (output_vsd_xml)
values (@output_vsd);

WITH XMLNAMESPACES (
    'http://api.vetrf.ru/schema/cdm/mercury/g2b/applications/v2' as merc,
    'http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2' as vd,
    'http://api.vetrf.ru/schema/cdm/dictionary/v2' as dt,
    'http://api.vetrf.ru/schema/cdm/base' as bs
)
update t set output_vsd_xml.modify('
    insert sql:variable("@consignor")
    as first into /merc:processIncomingConsignmentRequest[1]/merc:delivery[1]/vd:deliveryDate[1]'
)
from @t t;

select * from @t;

该表已经在您的代码中，只是未使用过：）

很遗憾，你没有说明你的预期输出，所以我的答案需要一些神奇的晶球请求。我很确定，这可以更容易解决：

DECLARE @output_vsd XML;

DECLARE @source_vsd XML =
N'<vd:vetDocument xmlns:vd="http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2">
    <vd:certifiedConsignment xmlns:vd="http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2">
    <vd:consignor xmlns:vd="http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2">
        <dt:businessEntity xmlns:dt="http://api.vetrf.ru/schema/cdm/dictionary/v2">
        <bs:uuid  xmlns:bs="http://api.vetrf.ru/schema/cdm/base">04ceb142-053d-11e1-99b4-d8d385fbc9e8</bs:uuid>
        </dt:businessEntity>
    </vd:consignor>
    <vd:consignee xmlns:vd="http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2">
        <dt:businessEntity xmlns:dt="http://api.vetrf.ru/schema/cdm/dictionary/v2">
        <bs:uuid  xmlns:bs="http://api.vetrf.ru/schema/cdm/base">cbee869d-5405-4181-a1d8-7e8c8af4597b</bs:uuid>
        </dt:businessEntity>
    </vd:consignee>
    </vd:certifiedConsignment>
</vd:vetDocument>';

- easy-cheesy ，我使用名称空间通配符和深度搜索和//

DECLARE @consignor xml = @source_vsd.query(N'//*:consignor[1]');

DECLARE @szLocalTransactionId nvarchar(max)= N'q1234';
DECLARE @szLogin nvarchar(max) = N'login';
DECLARE @szDeliveryDate nvarchar(max) = N'2015-09-28T17:17:00:00';

- 您可以在XML的一代中直接添加XML。不需要表格或任何.modify()的电话 - 至少我是这么认为的。不需要子选择，只需添加更深的嵌套。这可以使用XPath之类的别名来完成。否则你会反复得到你的命名空间声明（没错，但非常讨厌！）。

如果您需要添加名称空间dt和bs，只需添加它们即可。但是这里没有使用它们......

;WITH XMLNAMESPACES( 'http://api.vetrf.ru/schema/cdm/mercury/g2b/applications/v2' as merc,
                    'http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2' as vd)
SELECT @output_vsd = 
(
    SELECT  @szLocalTransactionId as [merc:localTransactionId],
            @szLogin as [merc:initiator/vd:login],
            @szDeliveryDate as [merc:delivery/vd:deliveryDate],
            @consignor as [merc:delivery/*]
    FOR XML PATH ('merc:processIncomingConsignmentRequest')
);

SELECT @output_vsd;

我不知道，发货人在哪里。这是我的输出：

<merc:processIncomingConsignmentRequest xmlns:vd="http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2" xmlns:merc="http://api.vetrf.ru/schema/cdm/mercury/g2b/applications/v2">
  <merc:localTransactionId>q1234</merc:localTransactionId>
  <merc:initiator>
    <vd:login>login</vd:login>
  </merc:initiator>
  <merc:delivery>
    <vd:deliveryDate>2015-09-28T17:17:00:00</vd:deliveryDate>
    <vd:consignor xmlns:vd="http://api.vetrf.ru/schema/cdm/mercury/vet-document/v2">
      <dt:businessEntity xmlns:dt="http://api.vetrf.ru/schema/cdm/dictionary/v2">
        <bs:uuid xmlns:bs="http://api.vetrf.ru/schema/cdm/base">04ceb142-053d-11e1-99b4-d8d385fbc9e8</bs:uuid>
      </dt:businessEntity>
    </vd:consignor>
  </merc:delivery>
</merc:processIncomingConsignmentRequest>

使用t-sql将xml插入另一个xml
