sql-server xml

Sql server 尝试读取XML的节点值时发生XML分析错误,sql-server,xml,sql-server-2014,Sql Server,Xml,Sql Server 2014,我有一个XML文件（TestArticles.XML），我需要将其导入SQL SERVER 2014，从各个节点读取数据，并将其插入同一数据库中的其他几个表中 TestArticles.xml <?xml version="1.0" encoding="UTF-8"?> <Articles> <sv:node sv:name="test1" xmlns:sv="http://www.jcp.org/jcr/sv/1.0" xmlns:xsi="http://

我有一个XML文件（TestArticles.XML），我需要将其导入SQL SERVER 2014，从各个节点读取数据，并将其插入同一数据库中的其他几个表中

TestArticles.xml

<?xml version="1.0" encoding="UTF-8"?>
<Articles>
<sv:node sv:name="test1"
    xmlns:sv="http://www.jcp.org/jcr/sv/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <sv:property sv:name="jcr:primaryType" sv:type="Name">
      <sv:value>mgnl:tax-article</sv:value>
    </sv:property>
    <sv:property sv:name="jcr:createdBy" sv:type="String">
      <sv:value>system</sv:value>
    </sv:property>
</sv:node>
<sv:node sv:name="test2"
    xmlns:sv="http://www.jcp.org/jcr/sv/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <sv:property sv:name="jcr:primaryType" sv:type="Name">
      <sv:value>mgnl:tax-article</sv:value>
    </sv:property>
    <sv:property sv:name="jcr:createdBy" sv:type="String">
      <sv:value>admin</sv:value>
    </sv:property>
</sv:node>  
</Articles>

使用OPENXML函数解析XML数据

在执行上述查询时，我得到以下提到的错误：

Msg 6603，16级，状态2，第14行 XML分析错误：引用了未声明的命名空间前缀：“sv”

我想从TestArticles.xml获取以下内容

sv:每个sv:节点的名称

sv:node中每个sv:property节点的sv:value

有人能帮我解决这个问题吗？

您需要先明确定义前缀，例如，使用和XQuery:

;WITH XMLNAMESPACES('http://www.jcp.org/jcr/sv/1.0' as sv)
SELECT c.value('@sv:name', 'varchar(100)') As Name
FROM ArticlesXML a
    CROSS APPLY ArticlesXMLData.nodes('Articles/sv:node') t(c)

通过此查询，您可以读取XML中的所有数据：

CREATE TABLE ArticlesXML
(
Id INT IDENTITY PRIMARY KEY,
ArticlesXMLData XML,
LoadedDateTime DATETIME
)
GO

SET IDENTITY_INSERT ArticlesXML ON;
INSERT INTO ArticlesXML(Id,ArticlesXMLData,LoadedDateTime) VALUES
(1,
'<?xml version="1.0" encoding="UTF-8"?>
<Articles>
<sv:node sv:name="test1"
    xmlns:sv="http://www.jcp.org/jcr/sv/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <sv:property sv:name="jcr:primaryType" sv:type="Name">
      <sv:value>mgnl:tax-article</sv:value>
    </sv:property>
    <sv:property sv:name="jcr:createdBy" sv:type="String">
      <sv:value>system</sv:value>
    </sv:property>
</sv:node>
<sv:node sv:name="test2"
    xmlns:sv="http://www.jcp.org/jcr/sv/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <sv:property sv:name="jcr:primaryType" sv:type="Name">
      <sv:value>mgnl:tax-article</sv:value>
    </sv:property>
    <sv:property sv:name="jcr:createdBy" sv:type="String">
      <sv:value>admin</sv:value>
    </sv:property>
</sv:node>  
</Articles>',GETDATE());
SET IDENTITY_INSERT ArticlesXML OFF;

WITH XMLNAMESPACES('http://www.jcp.org/jcr/sv/1.0' AS sv
                  ,'http://www.w3.org/2001/XMLSchema-instance' AS xsi)
SELECT Id
      ,Article.value('@sv:name','varchar(max)') AS ArticleName
      ,Property.value('@sv:name','varchar(max)') AS PropertyName
      ,Property.value('@sv:type','varchar(max)') AS PropertyType
      ,Property.value('sv:value[1]','varchar(max)') AS PropertyValue
      ,LoadedDateTime
FROM ArticlesXML
CROSS APPLY ArticlesXML.ArticlesXMLData.nodes('/Articles/sv:node') A(Article)
CROSS APPLY A.Article.nodes('sv:property') AS B(Property);
--CleanUp
--DROP TABLE ArticlesXML;

如果您想以某种方式查询（筛选、聚合…），您有几个机会：

将结果放入临时表中，并根据需要使用它
与声明的表变量相同
环绕并将其用作CTE

（看起来像这样）

或者您可以使用XQuery谓词（例如

.nodes（'/Articles/sv:node[sv:name=“test1”]”）

）

根据您在评论中给出的样本，编辑增强型选择以反映您阅读多值属性的需要：结果是：

谢谢你的回复。但在这里，我想根据where条件中的sv:name读取sv:property标记中的sv:value节点值。例如sv:value=3fe558bd-d3aa-4c27-a975-f5ee8abc497f，其中sv:name=“jcr:uuid”Btw:

来自OPENXML，在前后调用SPs是绝对过时的，不应该再使用了……非常感谢您的帮助。它真的帮助了我：）。我还需要你的一点帮助。如果此模式中有一个节点：admin1 admin2 admin3 admin4 admin5 admin6，那么在这种情况下，Property.value（'sv:value[1]”，'varchar（max'）作为PropertyValue对我不起作用。简言之，我需要所有的值：admin1，admin2，admin3，admin4，admin5。选择Id、Property.value（'sv:value[1]”、'varchar（max'）作为PropertyValue，从ArticlesXML交叉应用ArticlesXML.ArticlesXMLData.nodes（'/Articles/sv:node'）A（Article）交叉应用A.Article.nodes（'sv:Property'）作为B（Property）；上面的查询在这里不起作用。你能帮我吗？太酷了。你太棒了：）。非常感谢你的帮助。它确实帮助我解决了我的问题：）。再次非常感谢你的帮助。
