SQL Server 2016 XML Shredding

Question

一直想弄明白这个问题，但没有成功，看了好像10个帖子和其他一些例子，还有MS的帮助，没有共鸣，需要用下面的格式粉碎一些xml数据。

我目前走的路 试图使用xml程序 但我不能到达终点线 与openxml以及。试图提取xml底部高亮的数据。

EXEC sp_xml_preparedocument @hdoc OUTPUT, @CreditScoreXML 
SELECT * FROM OPENXML(@hdoc, '/<ncf_report xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://cp.com/rules/client">/admin/summary/account_status_counters')
WITH
(
  [Ref_Number] VARCHAR(10) 'product_reference',
  [current_account_type] VARCHAR(10) './account/@type',
  [current_account_type_description] VARCHAR(50) './account/@description',
  [current_account_type_description] VARCHAR(1) './account/@status'

你可以定义你的XML的命名空间，使用： WITH XMLNAMESPACES 语句，然后你可以使用 .value().

我不明白你到底想提取什么信息，但这应该会让你走上正确的道路（我只放了你的xml的第一行，以节省空间，你应该把整个XML片段放在 @xml 变量）。)

declare @xml xml set @xml='
    <ncf_report xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://cp.com/rules/client">
    ...
'

;WITH XMLNAMESPACES ('http://cp.com/rules/client' as ns1)
select 
 @xml.value('(ns1:ncf_report/ns1:admin/ns1:product_reference)[1]', 'varchar(10)') as Ref_Number
,@xml.value('(ns1:ncf_report/ns1:report/ns1:summary/ns1:account_status_counters/ns1:account[@type="current" and @status ="1"]/@description)[1]', 'varchar(50)') as CurrentDescription
,@xml.value('(ns1:ncf_report/ns1:report/ns1:summary/ns1:account_status_counters/ns1:account[@type="current" and @status ="1"])[1]', 'int') as CurrentStatus
,@xml.value('(ns1:ncf_report/ns1:report/ns1:summary/ns1:account_status_counters/ns1:account[@type="current" and @status =" "]/@description)[1]', 'varchar(50)') as CurrentDescription_2
,@xml.value('(ns1:ncf_report/ns1:report/ns1:summary/ns1:account_status_counters/ns1:account[@type="current" and @status =" "])[1]', 'int') as CurrentStatus_2

这个示例查询将提取：
