SqlServer表中XML类型字段查询操作

以前从未在SQLServer中使用过XML类型字段，偶尔遭遇，很是试验了几次方才通过。记录脚本以资纪念。

/****** Object:  Table [dbo].[XMLTest]    Script Date: 01/17/2012 16:15:04 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[XMLTest](
	[ID] [int] IDENTITY(1,1) NOT NULL,
	[XmlContent] [xml] NOT NULL,
 CONSTRAINT [PK_XMLTest] PRIMARY KEY CLUSTERED 
(
	[ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

DECLARE @XmlContent XML
Set @XmlContent='<book id="0001"><title>九阳真经</title><author>张三丰</author><price>10</price></book>'
--Select @XmlContent.query('/book/title')
SELECT @XmlContent.value('(/book/title)[1]', 'nvarchar(max)')
INSERT
INTO
	XMLTest (XmlContent)
VALUES
	(@xmlContent)
Set @XmlContent='<book id="0001"><title>九阴真经</title><author>张四丰</author><price>10。5</price></book>'

INSERT
INTO
	XMLTest (XmlContent)
VALUES
	(@xmlContent)

GO

SELECT *
FROM
	XMLTest
WHERE
	XmlContent.value('(/book/title)[1]', 'nvarchar(max)') LIKE  '%真经%'
GO
