SQL Server SQL for xml auto 添加根节点
今天从数据库中查询出xml，同时添加一个根节点
做了如下测试：
create table TestXmlQuery(
ID int identity(1,1) not null,
Name varchar(10)
)
go
insert into [TestXmlQuery] (Name) values('测试1')
insert into [TestXmlQuery] (Name) values('测试2')
insert into [TestXmlQuery] (Name) values('测试3')
insert into [TestXmlQuery] (Name) values('测试4')
select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml auto,type
得到如下结果：
<t myID="1" myName="测试1" />
<t myID="2" myName="测试2" />
<t myID="3" myName="测试3" />
<t myID="4" myName="测试4" />
select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml auto,elements
得到如下结果：
<t>
<myID>1</myID>
<myName>测试1</myName>
</t>
<t>
<myID>2</myID>
<myName>测试2</myName>
</t>
<t>
<myID>3</myID>
<myName>测试3</myName>
</t>
<t>
<myID>4</myID>
<myName>测试4</myName>
</t>
select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml raw
得到如下结果：
<row myID="1" myName="测试1" />
<row myID="2" myName="测试2" />
<row myID="3" myName="测试3" />
<row myID="4" myName="测试4" />
select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml raw,elements
得到如下结果：
<row>
<myID>1</myID>
<myName>测试1</myName>
</row>
<row>
<myID>2</myID>
<myName>测试2</myName>
</row>
<row>
<myID>3</myID>
<myName>测试3</myName>
</row>
<row>
<myID>4</myID>
<myName>测试4</myName>
</row>
select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml raw,elements,
相关文档：
在项目中，我们很多都用到了xml文件，无论是参数配置还是与其它系统的数据交互。
今天就来讲一下Java 中使用dom4j来操作XML文件。
我们需要引入的包：
//文件包
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileWriter;
//工具包
import java.util.Ite ......
