我正在尝试将一些 XML 导入 SQL，但它不起作用。这是我正在使用的 SQL：

INSERT INTO learnertest (LearnRefNumber, FamilyName,GivenNames ) 
SELECT learner.query('LearnRefNumber').value('.', 'VARCHAR(15)'),
       learner.query('FamilyName').value('.', 'VARCHAR(30)'), 
       learner.query('GivenNames').value('.', 'VARCHAR(30)')
FROM ( 
SELECT CAST(x AS XML)
FROM OPENROWSET(
     BULK 'D:\xmltest.xml',
     SINGLE_BLOB) AS T(x)
     ) AS T(x)
CROSS APPLY x.nodes('Message/Learner') AS X(learner);

这是XML

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

</Message>

查询运行没有错误，它只是不插入任何行。谁能解释我做错了什么？

因为您的Message元素在命名空间中，所以您的 xpath 也需要在该命名空间中，或者您需要告诉 SQL 假定默认命名空间。在这种简单的情况下，后者是更简单的选择：

;WITH XMLNAMESPACES(DEFAULT 'http://www.theia.org.uk/ILR/2012-13/1')
INSERT INTO learnertest (LearnRefNumber, FamilyName,GivenNames ) 
SELECT learner.query('LearnRefNumber').value('.', 'VARCHAR(15)'),
       learner.query('FamilyName').value('.', 'VARCHAR(30)'), 
        learner.query('GivenNames').value('.', 'VARCHAR(30)')
FROM ( 
SELECT CAST(x AS XML)
FROM OPENROWSET(
     BULK 'D:\xmltest.xml',
     SINGLE_BLOB) AS T(x)
     ) AS T(x)
CROSS APPLY x.nodes('Message/Learner') AS X(learner);

只需添加第一行就可以了。
