我经历了不同的搜索,发现了很多类似的帖子,其中给出了将XML转换为Tabular格式的解决方案。 下面是单行I列附加的示例数据,以及我到目前为止所做的基本查询。
<DS_systeminfo>
<Systeminfo>
<Property>CurrentLanguage</Property>
<Property_value>en-US</Property_value>
</Systeminfo>
<Systeminfo>
<Property>Manufacturer</Property>
<Property_value>LENOVO</Property_value>
</Systeminfo>
<Systeminfo>
<Property>SerialNumber</Property>
<Property_value>789654</Property_value>
</Systeminfo>
<Systeminfo>
<Property>Caption</Property>
<Property_value>ATTT</Property_value>
</Systeminfo>
<Property>Manufacturer</Property>
<Property_value>LENOVO</Property_value>
</Systeminfo>
<Systeminfo>
<Property>WindowsDirectory</Property>
<Property_value>C:\WINDOWS</Property_value>
</Systeminfo>
并且query
位于以下位置:
SELECT SerialNumber,
Cast(SystemInfoXML AS XML).value('(/DS_systeminfo/Systeminfo/Property)[1]', 'varchar(100)') AS Caption,
Cast(SystemInfoXML AS XML).value('(/DS_systeminfo/Systeminfo/Property_value)[1]', 'varchar(100)') AS Value
FROM TerminalsDetail
这只取得第一个节点的值,我想在一个查询中动态选择所有节点,可能正在使用cursor
。
给出的数据是单行的,我有100多行,我需要将其转换为表格格式。
任何建议都会有所帮助。

Declare @YourTable table (ID int,SystemInfoXML xml)
Insert Into @YourTable values
(1,'<DS_systeminfo><Systeminfo><Property>CurrentLanguage</Property><Property_value>en-US</Property_value></Systeminfo><Systeminfo><Property>Manufacturer</Property><Property_value>LENOVO</Property_value></Systeminfo><Systeminfo><Property>SerialNumber</Property><Property_value>789654</Property_value></Systeminfo><Systeminfo><Property>Caption</Property><Property_value>ATTT</Property_value></Systeminfo><Systeminfo><Property>Manufacturer</Property><Property_value>LENOVO</Property_value></Systeminfo><Systeminfo><Property>WindowsDirectory</Property><Property_value>C:\WINDOWS</Property_value></Systeminfo></DS_systeminfo>')
Select A.ID
,B.*
From @YourTable A
Cross Apply (
Select [Caption] = f.n.value('(Property)[1]','varchar(50)')
,[Value] = f.n.value('(Property_value)[1]','varchar(50)')
From A.SystemInfoXML.nodes('DS_systeminfo') t(n)
Cross Apply t.n.nodes('Systeminfo') f(n)
) B
返回
ID Caption Value
1 CurrentLanguage en-US
1 Manufacturer LENOVO
1 SerialNumber 789654
1 Caption ATTT
1 Manufacturer LENOVO
1 WindowsDirectory C:\WINDOWS

这样的事情:
WITH the_data AS (
SELECT CAST(SystemInfoXML AS XML) AS XML_DATA
FROM TerminalsDetail
)
SELECT
XML_DATA.query('/DS_systeminfo/Systeminfo/Property[1]') as Caption,
XML_DATA.query('/DS_systeminfo/Systeminfo/Property_value[1]') as Value
FROM cte
