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,root('myRoot')

得到如下结果：

<myRoot>

<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>

</myRoot>

select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml raw,type,root('myRoot')

得到如下结果：

<myRoot>

<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" />

</myRoot>

select t.ID as myID,t.Name as myName from [TestXmlQuery] as t for xml auto,type,root('myRoot')

得到如下结果

<myRoot>

<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" />

</myRoot>
