asp.net 调用 存储过程（带output 参数）

存储过程：

--建数据库

createdatabasetest

--建表

ifexists(select*fromdbo.sysobjectswhereid=object_id(N'[dbo].[laolao]')andOBJECTPROPERTY(id,N'IsUserTable')=1)
droptable[dbo].[laolao]
GO

CREATETABLE[dbo].[laolao](
[MyName][int]NOTNULL,
[Mycompany][varchar](20)COLLATEChinese_PRC_CI_ASNULL
)ON[PRIMARY]
GO

--在表里面插入1000记录

SETQUOTED_IDENTIFIERON
GO
SETANSI_NULLSON
GO

createprocps_InsertRow
as
declare@iINT

set@i=1000

while@i>0
begin
insertintolaolaovalues(cast(@iasvarchar(10)),cast(@iasvarchar(10))+'whn')
set@i=@i-1
end

GO
SETQUOTED_IDENTIFIEROFF
GO
SETANSI_NULLSON
GO

--一个带output参数的存储过程

SETQUOTED_IDENTIFIERON
GO
SETANSI_NULLSON
GO

ALTERprocDepartPage
@PageIndexint,
@PageSizeint,
@SumCountintoutput

as

begin

declare@RecordCountint
set@RecordCount=@PageIndex*@PageSize
set@SumCount=(selectCount(*)fromlaolao)
SETROWCOUNT@RecordCount
select*into#TempTablefromlaolaoorderbyMyNameasc
SETROWCOUNT@PageSize
select*from#TempTableorderbyMyNamedesc
SETROWCOUNT0
droptable#TempTable
end

GO
SETQUOTED_IDENTIFIEROFF
GO
SETANSI_NULLSON
GO
