Question

之前，请看：

SQL-Server XML-Bulk-Import and reading as table-data

这是一个以下问题。

XML：

<BMECAT>
    <T_NEW_CATALOG>
        <ARTICLE mode="new">
            <SUPPLIER_AID>9900026005</SUPPLIER_AID>
            <ARTICLE_DETAILS>
                <DESCRIPTION_SHORT>Totalstop fetra f. LF850x500mm</DESCRIPTION_SHORT>                    
                <EAN>4017976822105</EAN>
                <KEYWORD>FK_UNION</KEYWORD>
                <KEYWORD>starken</KEYWORD>
                <KEYWORD>Transport</KEYWORD>
                <KEYWORD>Große</KEYWORD>
                <KEYWORD>Lieferanten</KEYWORD>
                <KEYWORD>Zentralbremssystem</KEYWORD>
                <KEYWORD>Betriebseinrichtung_2016/18_(Online)</KEYWORD>
                <KEYWORD>TPE-Rolle</KEYWORD>
                <KEYWORD>Marken</KEYWORD>
                <KEYWORD>Unsere</KEYWORD>
                <KEYWORD>TOTALSTOP,</KEYWORD>
                <KEYWORD>TOTALSTOP</KEYWORD>
            </ARTICLE_DETAILS>
        </ARTICLE>
    </T_NEW_CATALOG>
</BMECAT>

对于每篇文章，<KEYWORD>都有不同的数量。当具有相同的名称时，如何在文章中获取所有关键字？

----------------------- UPDATE ----------------------- ----------------------

现在我拥有了我需要的所有内容并最终理解。这是整个工作代码：

DROP TABLE XMLwithOpenXML

CREATE TABLE XMLwithOpenXML
(
Id INT IDENTITY PRIMARY KEY,
XMLData XML,
LoadedDateTime DATETIME
)

INSERT INTO XMLwithOpenXML(XMLData, LoadedDateTime)
SELECT CONVERT(XML, BulkColumn) AS BulkColumn, GETDATE() 
FROM OPENROWSET(BULK '\\WINSER1\\proALPHA\\templates_eBus\\Test.xml', SINGLE_BLOB) AS x;

WITH Numbered AS
(
    SELECT Id          
          ,a.value('SUPPLIER_AID[1]','nvarchar(max)') AS SUPPLIER_AID
          ,kw.value('.','nvarchar(max)') AS Keyword
    FROM XMLwithOpenXML AS t
    CROSS APPLY t.XMLData.nodes('/BMECAT/T_NEW_CATALOG/ARTICLE') AS A(a)
    CROSS APPLY a.nodes('ARTICLE_DETAILS') AS B(ad)
    CROSS APPLY ad.nodes('KEYWORD') AS C(kw)
)
SELECT Id
      ,SUPPLIER_AID
      ,KEYWORD
FROM Numbered;

非常感谢!!!

Answer 1

您可以将ARTICLE_DETAILS的所有节点作为单独的行。

declare @x xml= '<BMECAT>
    <T_NEW_CATALOG>
        <ARTICLE mode="new">
            <SUPPLIER_AID>9900026005</SUPPLIER_AID>
            <ARTICLE_DETAILS>
                <DESCRIPTION_SHORT>Totalstop fetra f. LF850x500mm</DESCRIPTION_SHORT>                    
                <EAN>4017976822105</EAN>
                <KEYWORD>FK_UNION</KEYWORD>
                <KEYWORD>starken</KEYWORD>
                <KEYWORD>Transport</KEYWORD>
                <KEYWORD>Große</KEYWORD>
                <KEYWORD>Lieferanten</KEYWORD>
                <KEYWORD>Zentralbremssystem</KEYWORD>
                <KEYWORD>Betriebseinrichtung_2016/18_(Online)</KEYWORD>
                <KEYWORD>TPE-Rolle</KEYWORD>
                <KEYWORD>Marken</KEYWORD>
                <KEYWORD>Unsere</KEYWORD>
                <KEYWORD>TOTALSTOP,</KEYWORD>
                <KEYWORD>TOTALSTOP</KEYWORD>
            </ARTICLE_DETAILS>
        </ARTICLE>
    </T_NEW_CATALOG>
</BMECAT>';
 select t.n.query('.')
 from @x.nodes('BMECAT/T_NEW_CATALOG/ARTICLE/ARTICLE_DETAILS/*') t(n);

修改

根据您在编辑问题中的引用，我猜您需要值，包括KEYWORD的上层和独特的兄弟。它们仍然可以从KEYWORD节点访问。

select t.n.value('(/BMECAT/T_NEW_CATALOG/ARTICLE/@mode)[1]', 'varchar(50)') as mode, t.n.value('(/BMECAT/T_NEW_CATALOG/ARTICLE/SUPPLIER_AID)[1]', 'varchar(50)') as AID, t.n.value('(/BMECAT/T_NEW_CATALOG/ARTICLE/ARTICLE_DETAILS/DESCRIPTION_SHORT)[1]', 'varchar(50)') as DESCRIPTION_SHORT, t.n.value('(/BMECAT/T_NEW_CATALOG/ARTICLE/ARTICLE_DETAILS/EAN)[1]', 'varchar(50)') as EAN, t.n.value('.[1]', 'varchar(50)') as KEYWORD from @x.nodes('/BMECAT/T_NEW_CATALOG/ARTICLE/ARTICLE_DETAILS/KEYWORD') t(n)

Answer 2

尝试这样

DECLARE @xml XML=
'<BMECAT>
    <T_NEW_CATALOG>
        <ARTICLE mode="new">
            <SUPPLIER_AID>9900026005</SUPPLIER_AID>
            <ARTICLE_DETAILS>
                <DESCRIPTION_SHORT>Totalstop fetra f. LF850x500mm</DESCRIPTION_SHORT>                    
                <EAN>4017976822105</EAN>
                <KEYWORD>FK_UNION</KEYWORD>
                <KEYWORD>starken</KEYWORD>
                <KEYWORD>Transport</KEYWORD>
                <KEYWORD>Große</KEYWORD>
                <KEYWORD>Lieferanten</KEYWORD>
                <KEYWORD>Zentralbremssystem</KEYWORD>
                <KEYWORD>Betriebseinrichtung_2016/18_(Online)</KEYWORD>
                <KEYWORD>TPE-Rolle</KEYWORD>
                <KEYWORD>Marken</KEYWORD>
                <KEYWORD>Unsere</KEYWORD>
                <KEYWORD>TOTALSTOP,</KEYWORD>
                <KEYWORD>TOTALSTOP</KEYWORD>
            </ARTICLE_DETAILS>
        </ARTICLE>
    </T_NEW_CATALOG>
</BMECAT>';
SELECT a.value('@mode','nvarchar(max)') AS ARTICLE_mode
      ,a.value('SUPPLIER_AID[1]','nvarchar(max)') AS SUPPLIER_AID
      ,ad.value('DESCRIPTION_SHORT[1]','nvarchar(max)') AS DESCRIPTION_SHORT
      ,ad.value('EAN[1]','nvarchar(max)') AS EAN
      ,kw.value('.','nvarchar(max)')
FROM @xml.nodes('/BMECAT/T_NEW_CATALOG/ARTICLE') AS A(a)
CROSS APPLY a.nodes('ARTICLE_DETAILS') AS B(ad)
CROSS APPLY ad.nodes('KEYWORD') AS C(kw)

如果所有元素具有相同的名称，如何从XML检索数据？
