在项目中经常用XML文件,看看T-SQL程序设计发现SQLSERVER2005居然可以处理XML类型,而且还可以使用类似于Xpath的查询语法查询。

示例:
创建Table
代码如下:
CREATE TABLE [dbo].[xmlTable](
[id] [int] IDENTITY(1,1) NOT NULL,
[doc] [xml] NULL
)


一。插入数据
1.通过XML文件插入
1.xml
代码如下:


dafaf2
dafaf3
dafaf4


代码如下:
insert into xmlTable(doc)
select * from
openrowset(BULK 'C:\Documents and Settings\Administrator\桌面\1.xml',SINGLE_CLOB) as x

2.通过字符串插入
insert into xmlTable(doc) values('
123')

二。查询
select doc.value('(/dd/a[@id>2])[1]','nvarchar(50)') as xm from xmlTable
select * from xmlTable where doc.value('(/dd/a[@id>2])[1]','nvarchar(50)') ='博客园'
三。更新
1.插入节点
update xmlTable set doc.modify('insert 123 into (/dd)[1]')
注:insert 插入到
into --插入里面
after --插入节点后面
before --插入节点前面
2.删除节点
update xmlTable
set doc.modify('delete (/dd/a)[1]') --删除 /dd/a 的第一个节点
3.修改节点
update xmlTable
set doc.modify('replace value of (/dd/a/text())[1] with "博客园"')


暂时只学到这么多,以后再写。。。
