复制代码 代码如下:
–创建测试表
DECLARE @Users TABLE
(
ID INT IDENTITY(1,1),
UserInfo XML
)
—插入测试数据
DECLARE @xml XML
SET @xml='
<root>
<user>
<userid>1</userid>
<userName>test1</userName>
</user>
</root>'
INSERT INTO @Users(UserInfo)VALUES(@xml)
–插入单节点,(类型：as first，as last，after（默认），before)
UPDATE @Users SET UserInfo.modify('insert <address>shanghai</address>
into (/root/user)[1]')
–插入多节点以','分割
UPDATE @Users SET UserInfo.modify('insert (<firstName>steven</firstName>,
<lastName>shi</lastName>) into (/root/user)[1]')
— 增加属性
declare @editTime varchar(23);
set @editTime=CONVERT(VARCHAR(23), GETDATE(), 121);
UPDATE @Users SET UserInfo.modify(
N'insert (attribute editTime {sql:variable("@editTime")})
into(/root/user/userid)[1]'
)
–插入多属性以','分割
declare @aid float,@bid float
set @aid=0.5
UPDATE @Users SET UserInfo.modify('insert (attribute aid {sql:variable("@aid")},
attribute bid {"test"}
)
into (/root/user)[1]')
—插入注释
UPDATE @Users SET UserInfo.modify(N'insert <!– 注释 –>
before (/root/user/userid[1])[1]')
—插入处理指令
UPDATE @Users SET UserInfo.modify('insert <?Program = "A.exe" ?>
before (/root)[1]')
—插入CDATA
UPDATE @Users SET UserInfo.modify(N'insert <C><![CDATA[<city>北京</city> or cdata]]> </C>
after (/root/user)[1]')
—插入文本
UPDATE @Users SET UserInfo.modify(N'insert text{"插入文本"} as first
into (/root/user)[1]')
—根据 if 条件语句进行插入
—判断属性值
UPDATE @Users SET UserInfo.modify('insert if(/root/user[@ID=1]) then (<tel>888888</tel>)
else (<qq>66666</qq>)
into (/root/user)[1]')
—-判断节点Value
UPDATE @Users SET UserInfo.modify('insert if(/root/user[firstName="steven1"]) then (<tel>1111</tel>)
else (<qq>2222</qq>)
into (/root/user)[1]')
—-判断user 节点数是否小于等于10
UPDATE @Users SET UserInfo.modify('insert if (count(/root/user)<=10) then element user { "This is a new user" }
else () as last
into (/root)[1]')
SELECT * FROM @Users
–有命名空间的操作
–DECLARE @xml XML
— SET @xml='<root xmlns="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/users">
— <user>
— <userid>1</userid>
— <userName>test1</userName>
— </user>
— </root>'
— INSERT INTO Users(UserInfo)VALUES(@xml)
— UPDATE Users SET UserInfo.modify('
— declare namespace UI="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/users";
— insert <UI:user>
— <UI:firstName>steven2</UI:firstName>
— </UI:user> as first
— into (/UI:root)[1]')
— SELECT * FROM Users
— UPDATE Users SET UserInfo.modify('
— declare namespace UI="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/users";
— insert attribute ID { "55" }
— into (/UI:root/UI:user)[1]')
