將XML導入到SQL

Question

對不起，有關此主題的更多文章，但我絕望地試圖將這個XML導入到數據庫沒有任何成功。 這是XML：

<session xmlns="http://winscp.net/schema/session/1.0" start="2014-11-03T17:23:22.376Z"> 
    <ls> 
    <destination value="/Output" /> 
    <files> 
     <file> 
     <filename value="." /> 
     <type value="d" /> 
     <modification value="2014-11-03T12:17:58.000Z" /> 
     <permissions value="rwxr-sr-x" /> 
     </file> 
     <file> 
     <filename value="7215_SG.csv" /> 
     <type value="-" /> 
     <size value="1584161" /> 
     <modification value="2014-11-03T12:06:46.000Z" /> 
     <permissions value="rw-r--r--" /> 
     </file> 
     <file> 
     <filename value="6171_SG.csv" /> 
     <type value="-" /> 
     <size value="2298481" /> 
     <modification value="2014-11-03T12:05:13.000Z" /> 
     <permissions value="rw-r--r--" /> 
     </file> 
    </files> 
    <result success="true" /> 
    </ls> 
</session> 

這是sql語句導入XML：

 
SELECT 
    xmldata.value('(./filename/@value)[1]', 'NVARCHAR(50)') AS szFilename, 
    xmldata.value('(./type/@value)[1]', 'NVARCHAR(50)') AS szType, 
    xmldata.value('(./size/@value)[1]', 'NVARCHAR(50)') AS szSize, 
    xmldata.value('(./modification/@value)[1]', 'NVARCHAR(50)') AS szModification, 
    xmldata.value('(./permissions/@value)[1]', 'NVARCHAR(50)') AS szPermissions 
FROM 
    (SELECT CAST(x AS XML) 
    FROM OPENROWSET(BULK 'd:\temp\Test\log.xml', 
    SINGLE_BLOB) AS T(x)) AS T(x) 
CROSS APPLY 
    x.nodes('//session/ls/files/file') AS X(xmldata); 

你能幫助我，告訴我，我到底做錯了什麼？

在此先感謝！

您只需簡單地需要尊重您的XML根節點上定義的XML名稱空間！

<session xmlns="http://winscp.net/schema/session/1.0" 
     ******************************************** 

爲了適應這種XML命名空間，你需要在你的XQuery定義的 - 在我看來，最好的辦法是使用WITH XMLNAMESPACES聲明：

;WITH XMLNAMESPACES(DEFAULT 'http://winscp.net/schema/session/1.0') 
SELECT 
    xmldata.value('(./filename/@value)[1]', 'NVARCHAR(50)') AS szFilename, 
    xmldata.value('(./type/@value)[1]', 'NVARCHAR(50)') AS szType, 
    xmldata.value('(./size/@value)[1]', 'NVARCHAR(50)') AS szSize, 
    xmldata.value('(./modification/@value)[1]', 'NVARCHAR(50)') AS szModification, 
    xmldata.value('(./permissions/@value)[1]', 'NVARCHAR(50)') AS szPermissions 
FROM 
    (SELECT CAST(x AS XML) 
    FROM OPENROWSET(BULK 'd:\temp\Test\log.xml', SINGLE_BLOB) AS T(x)) AS T(x) 
CROSS APPLY 
    x.nodes('//session/ls/files/file') AS X(xmldata);
