Question

使用以下SQL，我生成2行并将它们包装在单独的soap信封中。

declare @XmlDoc xml
;with XMLNAMESPACES 
(
    'http://schemas.xmlsoap.org/soap/envelope/' as soapenv,  
    'http://amsa.com/contract/baserequestcontract/v1.0' as H1,
    'http://MyCompany.org/contract/mrmPerson/v1.0' as N1,
    'http://MyCompany.org/contracts/person' as N2,
    'http://MyCompany.org/contracts/demogTypes' as N3

）

select @XmlDoc = 
(
  select
    top 2
    PersonID as 'soapenv:Header/H1:PersonID',
    IsAuthorizedForUse as 'soapenv:Body/N1:SaveMRMPersonRequest/N1:Person/N2:PersonTier2/N2:AddressArray/N2:Address/N3:CommonDemogInfo/N3:IsAuth'
  from
    dbo.PersonDemogAddress
  for xml 
    path ('soapenv:Envelope'),
    root ('root'),
    type,
    elements xsinil

）
选择@XmlDoc

输出如下：

<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xmlns:N3="http://MyCompany.org/contracts/demogTypes" 
  xmlns:N2="http://MyCompany.org/contracts/person" 
  xmlns:N1="http://MyCompany.org/contract/mrmPerson/v1.0" 
  xmlns:H1="http://amsa.com/contract/baserequestcontract/v1.0" 
  xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">  
<soapenv:Envelope>
<soapenv:Header>
  <H1:PersonID>1</H1:PersonID>
</soapenv:Header>
<soapenv:Body>
  <N1:SaveMRMPersonRequest>
    <N1:Person>
      <N2:PersonTier2>
        <N2:AddressArray>
          <N2:Address>
            <N3:CommonDemogInfo>
              <N3:IsAuth>Y</N3:IsAuth>
            </N3:CommonDemogInfo>
          </N2:Address>
        </N2:AddressArray>
      </N2:PersonTier2>
    </N1:Person>
  </N1:SaveMRMPersonRequest>
</soapenv:Body>
</soapenv:Envelope>  
<soapenv:Envelope>
<soapenv:Header>
  <H1:PersonID>8</H1:PersonID>
</soapenv:Header>
<soapenv:Body>
  <N1:SaveMRMPersonRequest>
    <N1:Person>
      <N2:PersonTier2>
        <N2:AddressArray>
          <N2:Address>
            <N3:CommonDemogInfo>
              <N3:IsAuth>Y</N3:IsAuth>
            </N3:CommonDemogInfo>
          </N2:Address>
        </N2:AddressArray>
      </N2:PersonTier2>
    </N1:Person>
  </N1:SaveMRMPersonRequest>
</soapenv:Body>

然而，对于xml列＆lt; N3：IsAuth＆gt;，我想使用整个单词＆lt; N3：IsAuthorizedForUse＆gt;所以我只是将SELECT部分的上述查询改为

select  
  top 2  
    PersonID as 'soapenv:Header/H1:PersonID',  
    IsAuthorizedForUse as 'soapenv:Body/N1:SaveMRMPersonRequest/N1:Person/N2:PersonTier2/N2:AddressArray/N2:Address/N3:CommonDemogInfo/N3:IsAuthorizedForUse

我收到了这个错误：

Msg 103, Level 15, State 4, Line 16  
The identifier that starts with 'soapenv:Body/N1:SaveMRMPersonRequest/N1:Person/N2:PersonTier2/N2:AddressArray/N2:Address/N3:CommonDemogInfo/N3:IsAuthorizedForUse' is too long. Maximum length is 128.

有什么方法可以解决这个问题？遗憾的是，无法更改xml名称空间，元素名称和层次结构。谢谢！

Answer 1

SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON

将它置于起点它解决了我的问题

Answer 2

这是一个sql server错误。列名限制为128个字符。

使用FOR XML PATH时如何在列别名上解析最大长度128？
