TSQL读取基于元素属性的XML文件

Question

我需要帮助从我已发送的XML文件中提取数据（并且无法控制），通常不会有任何问题，但是此文件的结构方式让我感到困惑。下面的示例XML。我搜索的文章都没有，似乎在某种程度上，我需要

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<Entities TotalResults="3"> 
<Entity Type="testing"><Fields> 
<Field Name="type"><Value>Internal</Value></Field> 
<Field Name="name"><Value>Customer123</Value></Field> 
<Field Name="updated"><Value>Yes</Value></Field> 
</Fields></Entity> 
<Entity Type="testing"><Fields> 
<Field Name="type"><Value>External</Value></Field> 
<Field Name="name"><Value>CustomerABC</Value></Field> 
<Field Name="updated"><Value>Yes</Value></Field> 
</Fields></Entity> 
<Entity Type="testing"><Fields> 
<Field Name="type"><Value>Unknown</Value></Field> 
<Field Name="name"><Value>Customer456</Value></Field> 
<Field Name="updated"><Value>No</Value></Field> 
</Fields></Entity> 
</Entities> 

我要的是

实体的EntityType名称更新

1内部Customer123与此XML文件工作的解决方案是

2外部CustomerABC是

3未知Customer456没有

我可以从文件，但不是在我需要的格式的数据..

DECLARE @input XML 
SELECT @input = CAST(x AS XML)FROM OPENROWSET(BULK 'C:\Test.xml', SINGLE_BLOB) AS T(x) 


SELECT T1.steps.value('Value[1]', 'nvarchar(Max)') As EntityType 
    FROM @input.nodes('Entities/Entity/Fields/Field') AS Tbl(Scan) 
    CROSS APPLY Tbl.Scan.nodes('.') as T1(steps)  
    Where Tbl.Scan.value('(@Name)[1]', 'varchar(max)') = 'type' 


    SELECT 
    T1.steps.value('Value[1]', 'nvarchar(Max)') As Name 
    FROM @input.nodes('Entities/Entity/Fields/Field') AS Tbl(Scan) 
    CROSS APPLY Tbl.Scan.nodes('.') as T1(steps)  
    Where Tbl.Scan.value('(@Name)[1]', 'varchar(max)') = 'name' 

    SELECT 
    T1.steps.value('Value[1]', 'nvarchar(Max)') As Updated 
    FROM @input.nodes('Entities/Entity/Fields/Field') AS Tbl(Scan) 
    CROSS APPLY Tbl.Scan.nodes('.') as T1(steps)  
    Where Tbl.Scan.value('(@Name)[1]', 'varchar(max)') = 'updated' 

这给了我，每3个排三个独立的表，是有可能运行一个查询将返回的数据，因为我需要？

柜面有人有兴趣....我们没有下...

DECLARE @input XML 
DECLARE @Total int 
DECLARE @Count int 
DECLARE @workXMl XML 
DECLARE @Type varchar(max) 
DECLARE @Name varchar(max) 
DECLARE @Updated varchar(max) 
SELECT @input = CAST(x AS XML) 
FROM OPENROWSET(BULK 'C:\TEST.xml', SINGLE_BLOB) AS T(x) 

IF OBJECT_ID('tempdb..#XMLData') IS NOT NULL DROP TABLE #XMLData 
IF OBJECT_ID('tempdb..#1') IS NOT NULL DROP TABLE #1 

CREATE TABLE #XMLData(
    [Type] [varchar](max) Null, 
    [Name] [varchar](max) Null, 
    [Updated] [varchar](max) Null) 

SELECT T2.Loc.query('.') as Result into #1 
FROM @input.nodes('Entities/Entity/Fields') as T2(Loc) 

DECLARE my_cursor 
CURSOR FAST_FORWARD FOR 
Select Result from #1 
OPEN my_cursor 
FETCH NEXT FROM my_cursor INTO @workXML 
WHILE @@FETCH_STATUS = 0 
BEGIN 

SET @Updated = (SELECT @workXML.value('(Fields/Field[@Name="updated"])[1]', 'nvarchar(max)')) 
    SET @Name = (SELECT @workXML.value('(Fields/Field[@Name="name"])[1]', 'nvarchar(max)')) 
    SET @Type = (SELECT @workXML.value('(Fields/Field[@Name="type"])[1]', 'nvarchar(max)')) 

    INSERT INTO #XMLData 
    Values (@Type,@Name,@Updated) 

FETCH NEXT FROM my_cursor INTO @workXML 
END 
CLOSE my_cursor; 
DEALLOCATE my_cursor; 

Select * FROM #XMLData
