我尝试下载XML文件并将其导入SQL表。 下载工作正常，它会生成以下XML文件。

GeoPers.xml 

<?xml version="1.0" encoding="UTF-8"?>

        </Clocking_GetByDateRangeUtcResult>
    </Clocking_GetByDateRangeUtcResponse>

</soap:Envelope>

我使用以下查询将文件加载到SQL中：

SQL QUERY 

DECLARE @XmlFile XML

SELECT @XmlFile = BulkColumn  
FROM OPENROWSET(BULK 'C:\Temp\GeoDynamics\Downloads\GeoPers.xml', SINGLE_BLOB) x

SELECT 
    Id = resource.value('(Id)[1]', 'varchar(255)'),
    DateTimeUtc = resource.value('(DateTimeUtc)[2]', 'varchar(255)'),
    DateTimeLocal = resource.value('(DateTimeLocal)[3]', 'varchar(255)'),
    UserID = resource.value('(User/Id)[4]', 'varchar(255)'),
    UserName = resource.value('(User/Name)[5]', 'varchar(255)'),
    VehicleID = resource.value('(Vehicle/Id)[6]', 'varchar(255)'),
    VehicleCode = resource.value('(Vehicle/Code)[7]', 'varchar(255)'),
    VehicleName = resource.value('(Vehicle/Name)[8]', 'varchar(255)')
 FROM
@XmlFile.nodes('//Clocking_GetByDateRangeUtcResponse/Clocking_GetByDateRangeUtcResult/ClockingEntity') AS XTbl1(resource)

查询没有结果，甚至没有错误代码。我不知道查询中哪里出错了。

主要问题是您的XML有一个默认命名空间（http://www.geodynamics.be/webservices）。您需要使用the WITH XMLNAMESPACES directive为查询指定该命名空间。

正如在另一个答案中所提到的，您还需要修复XPath查询中的索引 - 它们都应该是[1]。

WITH XMLNAMESPACES (DEFAULT 'http://www.geodynamics.be/webservices')
SELECT 
    Id = resource.value('(Id)[1]', 'varchar(255)'),
    DateTimeUtc = resource.value('(DateTimeUtc)[1]', 'varchar(255)'),
    DateTimeLocal = resource.value('(DateTimeLocal)[1]', 'varchar(255)'),
    UserID = resource.value('(User/Id)[1]', 'varchar(255)'),
    UserName = resource.value('(User/Name)[1]', 'varchar(255)'),
    VehicleID = resource.value('(Vehicle/Id)[1]', 'varchar(255)'),
    VehicleCode = resource.value('(Vehicle/Code)[1]', 'varchar(255)'),
    VehicleName = resource.value('(Vehicle/Name)[1]', 'varchar(255)')
FROM
    @XmlFile.nodes('//Clocking_GetByDateRangeUtcResponse/Clocking_GetByDateRangeUtcResult/ClockingEntity') AS XTbl1(resource);

输出：

Id                af261a77-a35b-4778-a175-6fd50d00cde1
DateTimeUtc       2017-09-28T02:37:56Z
DateTimeLocal     2017-09-28T04:37:56
UserID            4975535a-2690-4492-bc7f-5e8a7d839cb9
UserName          Marcel De Doncker
VehicleID         52e01d9c-96fa-46ed-98fe-f62e1792f019
VehicleCode       7080
VehicleName       Auto: Dacia Dokker 1-PAE-120

Add Namespaces to Queries with WITH XMLNAMESPACES

这会奏效。您没有选择正确的命名空间;请使用WITH XMLNAMESPACES。其次，除Id元素外，您选择的索引错误;您指定的索引[n]将选择元素的第n次出现。你总是需要第一个。
