正在 SQL 服务器中提取 XML 字段

Question

我在 MIWOD table 中有 fldxml 列，其中包含多种类型的数据。如何显示 [fldxml] 列值，如下所示？

 Routing      Drawing
      1       C:\Users\XXX\Documents\LETTUCE_WHEEL.pdf

这是 [fldxml] 的样子

<fields> 
    <field1>1</field1>
    <field2>C:\Users\XXX\Documents\LETTUCE_WHEEL.pdf</field2>
</fields>

我想要这样的东西

Routing      Drawing:
   1         C:\Users\XXX\Documents\LETTUCE_WHEEL.pdf

我尝试使用以下

SELECT 
    MIWOD.fldXml('(field1/text())[1]', 'varchar(50)') as Routing,
    MIWOD.fldXml('(field1/text())[1]', 'varchar(50)') as Routing
FROM  
    [MISAMPCO].[dbo].[MIWOD]

但是我得到以下错误

Cannot find either column "MIWOD" or the user-defined function or aggregate "MIWOD.fldXml", or the name is ambiguous.

Answer 1

DECLARE @stuff xml

SET @stuff = '<fields><field1>1</field1><field2>C:\Users\Kinfe\Documents\LETTUCE_WHEEL.pdf</field2></fields>'

SELECT 
    Child.value('field1[1]', 'int') [**Routing:**], 
    Child.value('field2[1]', 'nvarchar(max)') [**Drawing:**]
FROM 
    @stuff.nodes('fields[1]') as N(Child)
