Question

我遇到了从.net传递到存储过程的xml有问题，下面是传递的xml

DECLARE @XMLDoc AS XML 

SET @XMLDoc = 
            '<ArrayOfProblemType xmlns:i="http://www.w3.org/2001/XMLSchema-instance" 
           xmlns="http://schemas.datacontract.org/2004/07/DatasetServices.JobServices.DataContracts">
        <ProblemType>
           <DateAdded>2011-08-10T11:19:35.187</DateAdded>
                 <EmailTemplate>testing email template</EmailTemplate>
           <ProblemDescription>No Money</ProblemDescription>
           <ProblemTypeId>4</ProblemTypeId>
           <SendEmail>true</SendEmail>
        </ProblemType>
        </ArrayOfProblemType>'

我正在尝试按如下方式提取数据

SELECT 
    ProblemData.Probs.value('(ProblemTypeId)[1]', 'int') as 'ID',   
    ProblemData.Probs.value('(DateAdded)[1]', 'Varchar(50)') as 'DateAdded'  
FROM  
    @XMLDoc.nodes('/ArrayOfProblemType/ProblemType') as ProblemData(Probs)

我没有收到任何错误，但我也没有收到任何数据。

我已经查看了提示给我的所有答案，但似乎没有xml中的xmlns命名空间。我怀疑我需要以某种方式删除它。有没有人在此之前遇到过这个问题？

Answer 1

您不尊重XML命名空间 - 您需要这样做！

试试这个：

;WITH XMLNAMESPACES('http://schemas.datacontract.org/2004/07/DatasetServices.JobServices.DataContracts' AS ns)
SELECT 
    ProblemData.Probs.value('(ns:ProblemTypeId)[1]', 'int') as 'ID',   
    ProblemData.Probs.value('(ns:DateAdded)[1]', 'Varchar(50)') as 'DateAdded'  
FROM  
    @XMLDoc.nodes('/ns:ArrayOfProblemType/ns:ProblemType') as ProblemData(Probs)

Answer 2

您需要使用WITH XMLNAMESPACES。

;WITH XMLNAMESPACES (default 'http://schemas.datacontract.org/2004/07/DatasetServices.JobServices.DataContracts')
SELECT ProblemData.Probs.value('(ProblemTypeId)[1]', 'int') as 'ID',   
       ProblemData.Probs.value('(DateAdded)[1]', 'Varchar(50)') as 'DateAdded'  
FROM  @XMLDoc.nodes('/ArrayOfProblemType/ProblemType') as ProblemData(Probs)
