使用带有XMLNS的OPENXML命令将XML导入SQL Server

用户名

我有以下代码将xml导入SQL

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)

SELECT @XML = XMLData FROM XMLwithOpenXML

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML

SELECT rid, uid
FROM OPENXML(@hDoc, '/PportTimetable/Journey')
WITH 
(
rid [varchar](50) '@rid',
uid [varchar](100) '@uid'
)

EXEC sp_xml_removedocument @hDoc
GO

我可以使代码正常工作,但是只有当它不包含xmlns信息时(如下所示),这是为什么?

xmlns:xsd =“ http://www.w3.org/2001/XMLSchema”

xmlns:xsi =“ http://www.w3.org/2001/XMLSchema-instance”

xmlns =“ http://www.thalesgroup.com/rtti/XmlTimetable/v8”

XML标头

<PportTimetable xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" timetableID="20161018020822" xmlns="http://www.thalesgroup.com/rtti/XmlTimetable/v8">
  <Journey rid="201610188012733" uid="P12733" trainId="2J27" ssd="2016-10-18" toc="AW">
</Journey>
</PportTimetable>

我建议OPENXML完全跳过这些内容,并在SQL Server中使用内置的本机XQuery支持:

declare @input XML = '<PportTimetable xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" timetableID="20161018020822" xmlns="http://www.thalesgroup.com/rtti/XmlTimetable/v8">
    <Journey rid="201610188012733" uid="P12733" trainId="2J27" ssd="2016-10-18" toc="AW">
    </Journey>
</PportTimetable>'

-- define your XML namespaces - here, there's only a single "default" namespace    
;WITH XMLNAMESPACES(DEFAULT 'http://www.thalesgroup.com/rtti/XmlTimetable/v8')
SELECT 
    RID = XC.value('@rid', 'varchar(50)'),
    UID = XC.value('@uid', 'varchar(20)'),
    TrainId = XC.value('@trainId', 'varchar(25)'),
    SSD = XC.value('@ssd', 'varchar(25)'),
    TOC = XC.value('@toc', 'varchar(20)')
FROM 
    @input.nodes('/PportTimetable/Journey') AS XT(XC)

使用XQuery.nodes()函数将XML“切碎”到XML片段的“内联”表中(<Journey>在此示例中,每个节点一个),然后使用该.value()函数从这些XML片段中逐个抓取各个元素和属性。
