Sql server 替换XML命名空间以使用XQUERY

我在表中的一列中有一个如下所示的示例输入

<OrderNotification xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <POSKI xmlns="http://MyCompany.co.nz">12345</POSKI>
    <BUKRS xmlns="http://MyCompany.co.nz">ABCD</BUKRS>
    <PRCTR xmlns="http://MyCompany.co.nz">1324</PRCTR>
</OrderNotification>

它没有返回任何输出，因为我没有正确引用节点。有人能帮忙吗

提前感谢

请尝试以下解决方案

SQL

-- DDL and sample data population, start
DECLARE @tbl TABLE (ID INT IDENTITY PRIMARY KEY, OrderNotification XML);
INSERT INTO @tbl (OrderNotification ) VALUES
(N'<OrderNotification xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <POSKI xmlns="http://MyCompany.co.nz">12345</POSKI>
    <BUKRS xmlns="http://MyCompany.co.nz">ABCD</BUKRS>
    <PRCTR xmlns="http://MyCompany.co.nz">1324</PRCTR>
</OrderNotification>');
-- DDL and sample data population, end

WITH XMLNAMESPACES ('http://MyCompany.co.nz' AS ns1)
SELECT ID
    , c.value('(ns1:BUKRS/text())[1]','VARCHAR(20)') AS BUKRS
    , c.value('(ns1:POSKI/text())[1]','VARCHAR(256)') AS POSKI
    , c.value('(ns1:PRCTR/text())[1]','VARCHAR(256)') AS PRCTR
FROM @tbl
    CROSS APPLY OrderNotification.nodes('/OrderNotification') AS t(c);

我对你感激不尽。我的用例比上面详述的要复杂一些。但是，我能够包装结果并将其插入表中以执行xquery。这是成功的，我得到了需要的结果。非常感谢你的帮助！！我对你感激不尽。我的用例比上面详述的要复杂一些。但是，我能够包装结果并将其插入表中以执行xquery。这是成功的，我得到了需要的结果。非常感谢你的帮助！！
