SQL Server XML数据解析(1)

     很久就想写总结一下SQL Server解析XML数据的常用方法了，下面就给出一些示例，有事没事，你也可以参照着示例自己动手尝试着实现一下自己的需求。

示例1：从XML中解析数据到表变量

DECLARE @ItemMessage XML 
DECLARE @ItemTable TABLE(ItemNumber INT PRIMARY KEY,ItemDescription NVARCHAR(300))
SET @ItemMessage=N'<ItemList> 
<Item> 
    <ItemNumber>1</ItemNumber> 
    <ItemDescription>XBox 360,超值</ItemDescription> 
</Item> 
<Item> 
    <ItemNumber>2</ItemNumber> 
    <ItemDescription>Windows Phone7,快来尝鲜吧</ItemDescription> 
</Item> 
</ItemList>'
INSERT INTO @ItemTable 
( 
ItemNumber, 
ItemDescription 
) 
SELECT T.c.value('(ItemNumber/text())[1]','INT'), 
T.c.value('(ItemDescription/text())[1]','NVARCHAR(300)') 
FROM @ItemMessage.nodes('/ItemList/Item') AS T(c)
SELECT ItemNumber, 
ItemDescription 
FROM @ItemTable

运行结果：

示例二： 解析带命名空间的XML数据

DECLARE @ItemMessage XML 
DECLARE @ItemTable TABLE(ItemNumber INT PRIMARY KEY,ItemDescription NVARCHAR(300))
SET @ItemMessage=N'<ItemList xmlns="http://cd.love.com/SOA"> 
<Item> 
    <ItemNumber>1</ItemNumber> 
    <ItemDescription>XBox 360,超值</ItemDescription> 
</Item> 
<Item> 
    <ItemNumber>2</ItemNumber> 
    <ItemDescription>Windows Phone7,快来尝鲜吧</ItemDescription> 
</Item> 
</ItemList>'
;WITH XMLNAMESPACES(DEFAULT 'http://cd.love.com/SOA') 
INSERT INTO @ItemTable 
( 
ItemNumber, 
ItemDescription 
) 
SELECT T.c.value('(ItemNumber/text())[1]','INT'), 
T.c.value('(ItemDescription/text())[1]','NVARCHAR(300)') 
FROM @ItemMessage.nodes('/ItemList/Item') AS T(c)
SELECT ItemNumber, 
ItemDescription 
FROM @ItemTable

运行结果：
