带参数输入和输出的存储过程

储存过程1
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:  <Author,,Name>
-- Create date: <Create Date,,>
-- Description: <Description,,>
-- =============================================
ALTER PROCEDURE [dbo].[tt]
@title nvarchar(50),
@id  int  output
AS
BEGIN
select @id=oid from dbo.StockNews where title=@title
END

储存过程2
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:  <Author,,Name>
-- Create date: <Create Date,,>
-- Description: <Description,,>
-- =============================================
ALTER PROCEDURE [dbo].[rr]
AS
BEGIN
declare @id int
set @id=0
exec dbo.tt @title = N'81只股票跌破政策底“一天行情”考验金融地产',@id=@id output
if @id<>0
begin
select content from dbo.StockNews where oid=@id
end
END

执行 exec [dbo].[rr]

注意：@id=@id output 输出的时候

--储存过程三（把前两个储存过程整合，使用raiserror）
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:  <Author,,Name>
-- Create date: <Create Date,,>
-- Description: <Description,,>
-- =============================================
ALTER PROCEDURE [dbo].[rr]
@title nvarchar(50)
AS
BEGIN
declare @id int
select @id=oid from dbo.StockNews where title=@title
if @@rowcount>0
begin
select content from dbo.StockNews where oid=@id
end
else
      begin
      raiserror('no recode found',10,1)
      end
END
--测试 exec rr @title='便宜货不再抢手 42只个股跌破5元(名单)'
