这是T-Sql xml query with namespace
的后续问题我有以下XML数据。我需要将其转换为SQL表。我使用了以下SQL查询：
declare @XML xml =

exec sp_executesql @SQL, N'@XML xml', @XML
当我运行查询时，它什么都不返回。声明命名空间时出现问题。找到解决方案。
答案 0 :(得分：1)
您正在构建动态SQL语句，但with xmlnamespaces部分不会使其进入动态SQL查询。
请注意，XPath区分大小写，因此请使用//R代替//r：
; with xmlnamespaces(default 'urn:schemas-microsoft-com:xml-analysis:rowset')
select t.n.value('C0[1]', 'varchar(100)') as r
from @xml.nodes('//R') as t(n)
打印：
/software/vcm/56/VCM-OS-Provisioning-Server-5.6.iso
要查找所有列的列表，您可以：
; with xmlnamespaces(default 'urn:schemas-microsoft-com:xml-analysis:rowset')
select T.N.value('local-name(.)', 'sysname')
from @XML.nodes('//R/child::*') as T(N)
打印：
C0
C1
C2
C3
