我以前从未使用过XML,但是受过将文档导入SQL Server表的任务。作为测试,我一直在使用我在网上找到的示例,现在,我仅尝试检索单个列:
DECLARE @X XML
SELECT @X=MC2016
FROM OPENROWSET (BULK 'C:\TEMP\Detail_2016.xml', SINGLE_BLOB) AS MEDPOP_2016(MC2016)
DECLARE @hdoc int
EXEC SP_XML_PREPAREDOCUMENT @hdoc OUTPUT, @X
select *
from openxml (@hdoc, '/Results/Record', 1)
with (
MemberID varchar(10)
)
EXEC SP_XML_REMOVEDOCUMENT @hdoc
当我在SSMS中执行此操作时,查询完成,但是即使知道有成千上万的记录,也得到零行输出。
我正在运行SQL Server2016。此处包含的XML文件太大,但这是第一条记录(已标识):
<?xml version="1.0" encoding="utf-8"?>

最终,我想将整个记录加载到表中,但是到目前为止,我什至无法读取单个列,也没有收到任何错误消息来指示我要寻找的方向。
我在这里想念什么?谢谢。
最好的问候, 科里

从注释中提供的链接中的代码开始,您可以使用以下代码:
DECLARE @X XML
SELECT @X=MC2016
FROM OPENROWSET (BULK 'c:\TEMP\Detail_2016.xml', SINGLE_BLOB) AS MEDPOP_2016(MC2016)
DECLARE @hdoc int
EXEC SP_XML_PREPAREDOCUMENT @hdoc OUTPUT, @X, '<myNs xmlns:ns1="http://www.dxcg.com/Results.xsd"/>'
;WITH XMLNAMESPACES ('http://www.dxcg.com/Results.xsd' as ns1)
select *
from openxml (@hdoc, '/ns1:Results/ns1:Record', 1)
with (
MemberID varchar(10)
)
结果:
注意:您发布的xml可能缺少根元素的结束标记 </Results>
