首先，需要将值放入类型为

XML

的declare变量或XML类型的数据表列中。由于XML包含名称空间，您必须首先使用XMLNAMESPACES在

中声明它们。您可以使用通配符语法（*：
），但最好尽可能具体
.nodes（）
调用将导航到
级别。以下所有元素都是简单的1:1
，易于阅读
您可以这样尝试：
DECLARE @xml XML=
N'<VehicleStatusResponse xmlns:ns2= 
  "http://fms-standard.com/rfms/v1.0.0/xsd/common/position" xmlns="http://fms-standard.com/rfms/v1.0.0/xsd/status">

更新：插入到表中
最简单的方法是像CTE一样包装这个电话
WITH XMLNAMESPACES(...)
,DerivedTableCTE AS
(
   The query here
)
INSERT INTO YourTable (col1, col2, col3, ...)
SELECT col1, col2, col3, ...
FROM DerivedTableCTE

如果删除或修改声明，则可以使用XML类型和XML方法。SQL Server XML类型仅支持UCS-2编码，不识别“独立”。下面的示例使用字符串操纵来调整声明。您需要根据实际的列类型更改数据类型，并且应该在INSERT
语句中指定一个显式的列列表。在本例中我省略了这一点，只是因为我不想假设实际的表列与XML中的元素名称匹配
DECLARE @xml xml;
DECLARE @xmlString nvarchar(MAX) = N'<?xml version="1.0" encoding="UTF-8" standalone="true"?>

您正在使用哪些数据库管理系统？（大多数产品的存储过程远远不符合ANSI SQL。）SQL Server Management Studio 2016@Jarlh上面的XML缺少最后的结束标记
。请澄清您的实际问题…谢谢，我在Shnugo处更改了它。问题是如何从xml文件中获取属性，然后插入到my表中？如果上面的xml是一个真实的word示例，那么没有什么不规则的…如果只有一个xml，这不会有什么区别，但通常我建议使用.nodes（）
首先导航到目标级别，并在较短的XPath
上使用值。您的查询将一遍又一遍地调用.value（）…很抱歉这么挑剔，但我总是避免在没有列列表的情况下使用这样的插入。@Shnugo，我完全同意显式列列表是一种最佳做法。我之所以省略它，只是因为这个问题没有包括目标表DDL，而且我不想假设列和元素名称是相同的。我会在我的回答中加上这个。
