SQL Server - 為xml列返回xml子節點

Question

給定表T列：

ID UNIQUEIDENTIFIER
CreatedDate DATETIME
XmlData XML

XmlData的結構如下：

<application>
    <details firstname="first" lastname="last">
        <statement>statement</statement>
    </details>
    <educationHistory>
        <education subject="subject1" />
        <education subject="subject2" />
    </educationHistory>
    <experienceHistory>
        <examiningExperienceHistory>
            <examiningExperience module="module1" />
            <examiningExperience module="module2" />
        </examiningExperienceHistory>
        <teachingExperienceHistory>
            <teachingExperience module="module1" />
            <teachingExperience module="module2" />
        </teachingExperienceHistory>
    </experienceHistory>
</application>

我需要像這樣返回一個提取物：

ID Date       FirstName LastName Education    ExaminingExp TeachingExp
-----------------------------------------------------------------------
1  02-10-2012 First     Last     <xmlextract> <xmlextract> <xmlextract>

到目前為止，我有：

SELECT ID,
       CreatedDate [Date],
       XmlData.value('(application/details/@firstname)[1]','varchar(max)') [FirstName],
       XmlData.value('(application/details/@lastname)[1]','varchar(max)') [LastName]
FROM T

我在最后三列中苦苦掙扎。 對於每個記錄，我需要列出教學/考試經驗和教育。 有人可以幫忙嗎？

Answer 1

使用.query來提取xml。

例如

select 
XmlData.query('/application/educationHistory/*'),
XmlData.query('/application/experienceHistory/examiningExperienceHistory/*'),
XmlData.query('/application/experienceHistory/teachingExperienceHistory/*')

Answer 2

嘗試這個：

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
