--创建XMLTable
create table XMLTable(Id int  IDENTITY (1, 1) primary key, XMLCol xml);  
go   
----------------------------------------------------------------------------------
--插入XML数据单条
insert into [XML].[dbo].[XMLTable]
           ([XMLCol]) 
           select * from 
openrowset(BULK ‘G:\Document\XMLDocument\x3.xml‘,SINGLE_CLOB) as x
----------------------------------------------------------------------------------
--插入XML数据单条
DECLARE  @s varchar(100)
SET @s = ‘<Cust><Fname>Andrew</Fname><Lname>Fuller</Lname></Cust>‘ 
INSERT INTO [XML].[dbo].[XMLTable]
           ([Id],[XMLCol])
VALUES(3,cast(@s as xml))
GO

----------------------------------------------------------------------------------
--查询XMLTable数据表
select * from XMLTable
----------------------------------------------------------------------------------
--循环插入100万条数据

--XML主索引  
create primary xml index IPXML_XMLTable_XMLCol on XMLTable(XMLCol);  
--XML路径辅助索引  
create xml index IXML_XMLTable_XMLCol_Path on XMLTable(XMLCol)  
using xml index IPXML_XMLTable_XMLCol for path  
--XML属性辅助索引  
create xml index IXML_XMLTable_XMLCol_Property on XMLTable(XMLCol)  
using xml index IPXML_XMLTable_XMLCol for Property  
--XML内容辅助索引  
create xml index IXML_XMLTable_XMLCol_value on XMLTable(XMLCol)  
using xml index IPXML_XMLTable_XMLCol for value 
----------------------------------------------------------------------------------
--查询语句
select TOP 1000  XMLCol.query(‘(/authorinfo/personinfo)[1]‘) as xm from XMLTable

select * from xmlTable where XMLCol.value(‘(/authorinfo/personinfo/firstname)[1]‘,‘nvarchar(50)‘) =‘维春‘

select XMLCol.query(‘(/dd/a[@id>2])[1]‘) as xm from XMLTable
