SQLServerTable中XML列的操作代码

SQL Server Table中XML列的操作代码，需要的朋友可以参考下。

--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=' 
 
 
1 
test1 
 
' 
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 shanghai 
into (/root/user)[1]') 
--插入多节点以','分割 
UPDATE @Users SET UserInfo.modify('insert (steven, 
shi) 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  
before (/root/user/userid[1])[1]') 
---插入处理指令 
UPDATE @Users SET UserInfo.modify('insert  
before (/root)[1]') 
---插入CDATA 
UPDATE @Users SET UserInfo.modify(N'insert 北京 or cdata]]>  
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 (888888) 
else (66666) 
into (/root/user)[1]') 
----判断节点Value 
UPDATE @Users SET UserInfo.modify('insert if(/root/user[firstName="steven1"]) then (1111) 
else (2222) 
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=' 
--  
-- 1 
-- test1 
--  
-- ' 
-- 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  
-- steven2 
--  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]')
