时间：2010-09-04 来源：ITLOVER

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：
