這裏是我的xml文件:約節省的XDocument到SQL Server XML列
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://mfisoft.ru/soap" xmlns:ns2="http://xml.apache.org/xml-soap" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<ns1:selectRowsetResponse>
<result SOAP-ENC:arrayType="ns2:Map[1]" xsi:type="SOAP-ENC:Array">
<item xsi:type="ns2:Map">
<item>
<key xsi:type="xsd:string">report_id</key>
<value xsi:type="xsd:string">246</value>
</item>
</item>
</result>
</ns1:selectRowsetResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
,這是我在SQL Server表
CREATE TABLE [dbo].[HowToSaveXML](
[ID] [int] NOT NULL,
[XMLcontent] [xml] NOT NULL
)
當我寫在SQL Server Management Studio中這樣的SQL命令
insert into HowToSaveXML values (5,'<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://mfisoft.ru/soap" xmlns:ns2="http://xml.apache.org/xml-soap" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<ns1:selectRowsetResponse>
<result SOAP-ENC:arrayType="ns2:Map[1]" xsi:type="SOAP-ENC:Array">
<item xsi:type="ns2:Map">
<item>
<key xsi:type="xsd:string">report_id</key>
<value xsi:type="xsd:string">246</value>
</item>
</item>
</result>
</ns1:selectRowsetResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>')
它工作正常,併成功地向表中添加一條記錄HowToSaveXML
,但是當我使用C#代碼做同樣的事情,就像這樣:
XDocument xd = XDocument.Load(@"D:\temp\0919\sDocumentToXML.xml");
sqlCmdUpdate = new SqlCommand("insert into HowToSaveXML values (5 , " + xd.ToString(), conn);
sqlCmdUpdate.CommandTimeout = 200;
if (conn.State == ConnectionState.Closed)
conn.Open();
try
{
sqlCmdUpdate.ExecuteNonQuery();
}
catch (Exception aep)
{
}
其中sDocumentToXML.xml包含上面的文件相同的內容,但它拋出一個異常:
Incorrect syntax near '<'.
The label 'xmlns' has already been declared. Label names must be unique within a query batch or stored procedure
它似乎系統不允許重複節點,但我已經成功地插入相同的XML通過使用插入命令直接在管理工作室,那麼是什麼原因,我怎樣才能使用C#代碼做同樣的事情?謝謝。
加:如果我改變這樣
sqlCmdUpdate = new SqlCommand("insert into HowToSaveXML values (5 , '" + xd.ToString() + "'", conn);
C#代碼,它也拋出一個異常。
感謝ü您的回覆,現在它的工作原理 – yangl
