TSQL分解XML-使用名称空间

Here's a link to my previous question on this same block of code with a working shred example

好的,我是一个C#ASP.NET开发人员,遵循以下命令:获取给定的数据集,分解XML并返回列。我认为在ASP.NET端进行分解比较容易,因为我们已经可以访问反序列化程序等,以及已知类型的整个复合体,但是没有,老板说“在服务器上分解它,返回一个数据集,将数据集绑定到gridview的列”,所以现在,我正在做我被告知的事情。这些都是为了阻止那些会说“不好的要求”的人。

手头的任务:

如果我们修改了前一篇文章以在XML元素中包含名称空间,那么我们就失去了前一篇文章所具有的功能。。。

DECLARE @table1 AS TABLE (
    ProductID    VARCHAR(10)
  , Name         VARCHAR(20)
  , Color        VARCHAR(20)
  , UserEntered  VARCHAR(20)
  , XmlField     XML
)

INSERT INTO @table1 SELECT '12345','ball','red','john','<sizes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><size xmlns="http://example.com/ns" name="medium"><price>10</price></size><size xmlns="http://example.com/ns" name="large"><price>20</price></size></sizes>'

DECLARE @x XML
-- I think I'm supposed to use WITH XMLNAMESPACES(...) here but I don't know how
SELECT @x = (
    SELECT 
        ProductID
      , Name
      , Color
      , UserEntered
      , XmlField.query('
            for $vehicle in //auto
            return <auto 
                type = "{$vehicle/type}"
                wheels = "{$vehicle/wheels}"
                doors = "{$vehicle/doors}"
                cylinders = "{$vehicle/cylinders}"
            />')
    FROM @table1 table1
    WHERE Name = 'auto'
    FOR XML AUTO
)

SELECT @x

SELECT 
    ProductID    = T.Item.value('../@ProductID', 'varchar(10)')
  , Name         = T.Item.value('../@Name', 'varchar(20)')
  , Color        = T.Item.value('../@Color', 'varchar(20)')
  , UserEntered  = T.Item.value('../@UserEntered', 'varchar(20)')
  , VType        = T.Item.value('@type' , 'varchar(10)')
  , Wheels       = T.Item.value('@wheels', 'varchar(2)')
  , Doors        = T.Item.value('@doors', 'varchar(2)')
  , Cylinders    = T.Item.value('@cylinders', 'varchar(2)')
FROM   @x.nodes('//table1/auto') AS T(Item)

如果我以前的文章显示有更好的方法来做这件事,那么我真的需要修改这个问题,但在关闭的机会,这种编码风格是好的,我可能会继续这样做。
