如何在MS SQL中的XML字段中检索字段?
每当我使用此XML代码时,我尝试的每个查询都无法正常工作: 我想选择AccNumber值。
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Header>
<AuthSoapHd xmlns="https://temp.uri.com/Mngmt/">
<System>System1</System>
</AuthSoapHd>
</soap:Header>
<soap:Body>
<PrintList xmlns="https://temp.uri.com/Mngmt/">
<Account>
<AccNumber xmlns="https://temp.uri.com/Project/Object/Data">990368644</AccNumber>
</Account>
</PrintList>
</soap:Body>
</soap:Envelope>
我尝试了以下几个没有成功的变种
Select [RequestXML].query('/Envelope/Body/PrintList/Account/AccNumber')
FROM [dbo].[Table1]
答案 0 :(得分:4)
您忽略了正在使用的XML命名空间 - 您需要注意这一点!
WITH XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS soap,
'https://temp.uri.com/Project/Object/Data' AS data,
'https://temp.uri.com/Mngmt/' AS mgmt)
SELECT
RequestXML.value('(/soap:Envelope/soap:Body/mgmt:PrintList/mgmt:Account/data:AccNumber)[1]',
'BIGINT') AS 'AccNumber'
FROM
[dbo].[Table1]
希望有效!
