SQLSERVER 2005中使用sql语句对xml文件和其数据的进行操作(很全面)

-用SQL多条可以将多条数据组成一棵XML树L一次插入

--将XML树作为varchar参数传入用

--insert xx select xxx from openxml() 的语法插入数据

-----------------------------------导入，导出xml--------------------------

--1导入实例

--单个表

create table Xmltable(Name nvarchar(20),Nowtime nvarchar(20))

declare @s as nvarchar(2000);

set @s = N''

<Xmltables>

<Xmltable Name="1" Nowtime="1900-1-1">0</Xmltable>

<Xmltable Name="2" Nowtime="1900-1-1">0</Xmltable>

<Xmltable Name="3" Nowtime="1900-1-1">0</Xmltable>

<Xmltable Name="4" Nowtime="1900-1-1">0</Xmltable>

<Xmltable Name="5" Nowtime="1900-1-1">0</Xmltable>

</Xmltables>'';

declare @idHandle as int ;

EXEC sp_xml_preparedocument @idHandle OUTPUT, @s

insert into Xmltable(Name,Nowtime)

select * from openxml(@idHandle,N''/Xmltables/Xmltable'')

with dbo.xmltable

EXEC sp_xml_removedocument @idHandle

select * from Xmltable

-----------------------读入第二个表数据--------------------

create table Xmlta(Name nvarchar(20),Nowtime nvarchar(20))

declare @s as nvarchar(4000);

set @s =N''

<Xmltables>

<Xmltb Name="6" Nowtime="1900-2-1">0</Xmltable>

<Xmlta Name="11" Nowtime="1900-2-1">0</Xmlta>

</Xmltables>

'';

declare @idHandle as int ;

EXEC sp_xml_preparedocument @idHandle OUTPUT, @s

insert into Xmlta(Name,Nowtime)

select * from openxml(@idHandle,N''/Xmltables/Xmlta'')

with dbo.xmlta

EXEC sp_xml_removedocument @idHandle

select * from Xmlta

drop table Xmlta

-----------------------同时读入多表数据----------------

create table Xmlta(Name nvarchar(20),Nowtime datetime)

create table Xmltb(Name nvarchar(20),Nowtime datetime)

declare @s as nvarchar(4000);

set @s =N''

<Xmltables>

<Xmlta Name="1" Nowtime="1900-2-1">0</Xmlta>

<Xmltb Name="2" Nowtime="1900-2-1">0</Xmltb>

</Xmltables>

'';

--<Xmlta ></Xmlta> 则插入的数据为null

declare @idHandle as int ;

EXEC sp_xml_preparedocument @idHandle OUTPUT, @s

--表a

insert into Xmlta(Name,Nowtime)

select * from openxml(@idHandle,N''/Xmltables/Xmlta'')

with dbo.Xmlta

--表b

insert into Xmltb(Name,Nowtime)

select * from openxml(@idHandle,N''/Xmltables/Xmltb'')

with dbo.Xmltb

EXEC sp_xml_removedocument @idHandle

select * from Xmlta

select * from Xmltb

drop table Xmlta,Xmltb

--生成xml文件单表

DECLARE @xVar XML

SET @xVar = (SELECT * FROM Xmltable FOR XML AUTO,TYPE)

select @xVar

--1读取xml文件插入表中

DECLARE @hdoc int

DECLARE @doc xml

select @doc=BulkColumn from (SELECT *

FROM OPENROWSET(BULK ''E:\xml.xml'',SINGLE_BLOB) a)b

EXEC sp_xml_preparedocument @hdoc OUTPUT,@doc

SELECT * into #temp

FROM OPENXML (@hdoc,N''/root/dbo.xmltable'')

with (name nvarchar(20),Intro nvarchar(20))

exec sp_xml_removedocument @hdoc

--2读取xml文件插入表中

SELECT * into #temp FROM OPENROWSET(

BULK ''E:\xml.xml'',SINGLE_BLOB) AS x

DECLARE @hdoc int

DECLARE @doc xml

select @doc=BulkColumn from #temp

EXEC sp_xml_preparedocument @hdoc OUTPUT,@doc

SELECT * into #temp2

FROM OPENXML (@hdoc,N''/root/dbo.xmltable'')

with (name nvarchar(20),Intro nvarchar(20))

exec sp_xml_removedocument @hdoc

/*

---空的处理

<dbo.xmltable name="1" Intro="" />

<dbo.xmltable name="2" />

<dbo.xmltable name="3" Intro="c" />

1

2 NULL

3 c

*/

drop table xmlt

------------------------------------xml数据操作------------------

--类型化的XML

CREATE TABLE xmlt(ID INT PRIMARY KEY, xCol XML not null)

--T-sql生成数据

insert into xmlt values(1,

''<Xmltables>

<Xmltable Name="1" NowTime="1900-1-1">1</Xmltable>

<Xmltable Name="2" NowTime="1900-1-2">2</Xmltable>

<Xmltable Name="3" NowTime="1900-1-3">3</Xmltable>

<Xmltable Name="4" NowTime="1900-1-4">4</Xmltable>

<Xmltable Name="5" NowTime="1900-1-5">5</Xmltable>

</Xmltables>'')

--dataset生成数据

insert into xmlt values(2,

''<?xml version="1.0" encoding="gb2312" ?>

<Xmltables>

<Xmltable><Name>1</Name><NowTime>1900-1-1</NowTime>1</Xmltable>

<Xmltable><Name>2</Name><NowTime>1900-1-2</NowTime>2</Xmltable>

<Xmltable><Name>3</Name><NowTime>1900-1-3</NowTime>3</Xmltable>

</Xmltables>'')

--读取Name=1 的節點，請使用

SELECT xCol.query(''/Xmltables/Xmltable[@Name="1"]'') from xmlt where ID =1

--读取Name=1 的節點值，請使用

SELECT xCol.query(''/Xmltables/Xmltable[@Name="1"]/text()'') from xmlt where ID =1

--读取Name=5 的Name 屬性值，請使用

SELECT xCol.query(''data(/Xmltables/Xmltable[@Name])[5]'') from xmlt where ID =1

--读取所有节点Name

SELECT nref.value(''@Name'', ''varchar(max)'') LastName

FROM xmlt CROSS APPLY xCol.nodes(''/Xmltables/Xmltable'') AS R(nref) where ID=1

--读取所有节点NowTime

SELECT nref.value(''@NowTime'', ''varchar(max)'') LastName

FROM xmlt CROSS APPLY xCol.nodes(''/Xmltables/Xmltable'') AS R(nref) where ID=1

SELECT xCol.query(''data(/Xmltables/Xmltable[@Name=5]/@NowTime)[1]'') from xmlt where ID =1

--读取Name=1 的Name 屬性值

SELECT xCol.value(''data(/Xmltables/Xmltable//Name)[1]'',''nvarchar(max)'') FROM xmlt where ID=2

--读取NowTime=1 的NowTime 屬性值

SELECT xCol.value(''data(/Xmltables/Xmltable/NowTime)[1]'',''nvarchar(max)'') FROM xmlt where ID=2

--SELECT xCol.value(''data(/Xmltables/Xmltable[@Name])[1]'',''nvarchar(max)'') FROM xmlt where ID=2

------------------------------------------函数使用----------------

--query()、exist()

SELECT pk, xCol.query(''/root/dbo.xmltable/name'') FROM docs

SELECT xCol.query(''/root/dbo.xmltable/name'') FROM docs

WHERE xCol.exist (''/root/dbo.xmltable'') = 1

--modify()

UPDATE docs SET xCol.modify(''

insert

<section num="2">

<heading>Background</heading>

</section>

after (/doc/section[@num=1])[1]'')

--value()

SELECT xCol.value(''data((/root/dbo.xmltable//name))[2]'',''nvarchar(max)'') FROM docs

where pk=3

--nodes()

SELECT nref.value(''@Name'', ''varchar(max)'') LastName

FROM xmlt CROSS APPLY xCol.nodes(''/Xmltables/Xmltable'') AS R(nref)

--query()、value()、exist() 和nodes()，modify()

SELECT CAST(T.c as xml).query(''/root/dbo.xmltable/name'')

FROM OPENROWSET(BULK ''E:\xml.xml'',SINGLE_BLOB) T(c)
