Use .query
to extract xml. 使用
.query
来提取xml。
eg 例如
select
XmlData.query('/application/educationHistory/*'),
XmlData.query('/application/experienceHistory/examiningExperienceHistory/*'),
XmlData.query('/application/experienceHistory/teachingExperienceHistory/*')
Try this: 尝试这个:
SELECT ID, Created [DATE]
XmlData.value('(application/details/@firstname)[1]','varchar(max)') [FirstName],
XmlData.value('(application/details/@lastname)[1]','varchar(max)') [LastName],
XmlData.query('/application/educationHistory'),
XmlData.query('/application/experienceHistory/examiningExperienceHistory'),
XmlData.query('/application/experienceHistory/teachingExperienceHistory')
FROM T
