Question

我有一个我在SQL Server 2012中查询的示例XML架构。我有一个带有XML列的表。我希望在返回每一行时包含xml片段。

以下是现有查询和更详细的说明。

示例查询

;WITH XMLNAMESPACES (Default 'http://www.w3.org/2001/XMLSchema' )
  SELECT 
     a.value('@Number[1]', 'int') as Number
    ,b.value('(@FormId)[1]', 'NVARCHAR(50)') Form
  --,XmlDocument.query('Doc/Forms') as FormXml, 
    ,c.value('@ItemGuid[1]', 'uniqueidentifier') as ItemGuid
    ,c.value('@ItemNumber[1]', 'INT') AS ItemNumber
    ,d.value('(@Name)[1]','nvarchar(50)') As  Visitor
    ,d.value('(@Location)[1]','nvarchar(50)') As Location
    ,e.value('(@Name)[1]', 'NVARCHAR(50)') As Sender        
  FROM
    XmlTable As X
  CROSS APPLY XmlDocument.nodes('Doc') As aa(a)
  CROSS APPLY a.nodes('Forms') As bb(b)
  CROSS APPLY b.nodes('*') As cc(c)
  CROSS APPLY c.nodes('Visitors/Visitor') as dd(d)
  CROSS APPLY c.nodes('Senders/Sender') as ee(e)

我想要做的是在Form列之后包含xml片段，以显示它来自的片段。

我正在尝试这个

    XmlDocument.query('Doc/Forms') as FormXml,

以上是从该元素返回，我只想返回与<dev:Forms FormId="A1">相关的每一行的</dev:A1>到A1的所有内容。因此，当Form为A2时，我想要A2 - /A2＆lt; ---之间的所有内容

Answer 1

我相信你想得到的是b“表”所引用的XML，不是吗？

试试这一行：

, b.query('.') as FormXml

这会让你想要你想要的吗？它应该为您提供<Forms>节点的XML。

SQL Server：使用value，nodes方法返回相关的xml
