问题描述
使用以下SQL,我将生成2行并将其包装在单独的肥皂信封中.
With the following SQL, I am generating 2 rows and wrapping them in individual soap envelopes.
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
)
select @XmlDoc
输出看起来像这样:
<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>
但是,对于xml列< N3:IsAuth>,我想使用整个< N3:IsAuthorizedForUse>,所以我只是将上述查询的SELECT部分更改为
However, for the xml column < N3:IsAuth >, I want to use the whole word < N3:IsAuthorizedForUse > so I simply changed SELECT part of above query as
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
我收到此错误:
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.
有什么办法解决这个问题?遗憾的是,不能更改xml名称空间,元素名称和层次结构.谢谢!
Any way to solve this? The xml namespaces, element names and hierarchy cannot be changed unfortunately. Thanks!
推荐答案
SET QUOTED_IDENTIFIER OFF
SET ANSI_NULLS ON
将其放在开始时就解决了我的问题
place this at the starting it solved my problem
