--测试数据

DECLARE @pFileters VARCHAR(max)

SET @pFileters =

' <CountryId>

<Country _Id="AFG" Status="1" >Afghanistan </Country>

</CountryId>'

--1

DECLARE @idoc INT

EXEC sp_xml_preparedocument @idoc OUTPUT, @pFileters

SELECT *

FROM OPENXML (@idoc, '/CountryId/Country',2)

with (a varchar(50) './@_Id',b varchar(50) './@Status',C varchar(50) '.' )

--2

SELECT *

FROM OPENXML (@idoc, '/CountryId/Country',1)

with (_Id varchar(50),Status varchar(50),C varchar(50) '.' )

EXEC sp_xml_removedocument @idoc

--3

DECLARE @p xml

SET @p =

' <CountryId>

<Country _Id="AFG" Status="1" >Afghanistan </Country>

</CountryId>'

SELECT

A.x.value('@Status','int') AS b,

A.x.value('.','varchar(20)') AS C

FROM @p.nodes('//Country') AS A(x)

--结果
