存储过程返回参数的三种方法

CREATE TABLE [dbo].[Order](

[o_id] [bigint] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,

[o_buyerid] [int] NOT NULL

)

1.OUPUT参数返回值

例： 向Order表插入一条记录,返回其标识

CREATE PROCEDURE [dbo].[nb_order_insert](

@o_buyerid int ,

@o_id bigint OUTPUT

)

AS

BEGIN

SET NOCOUNT ON;

BEGIN

INSERT INTO [Order](o_buyerid )

VALUES (@o_buyerid )

SET @o_id = @@IDENTITY

END

END

存储过程中获得方法：

DECLARE @o_buyerid int

DECLARE @o_id bigint

EXEC [nb_order_insert] @o_buyerid ,o_id bigint

2 RETURN过程返回值

CREATE PROCEDURE [dbo].[nb_order_insert](

@o_buyerid int ,

@o_id bigint OUTPUT

)

AS

BEGIN

SET NOCOUNT ON;

IF(EXISTS(SELECT * FROM [Shop] WHERE [s_id] = @o_shopid))

BEGIN

INSERT INTO [Order](o_buyerid )

VALUES (@o_buyerid )

SET @o_id = @@IDENTITY

RETURN 1 — 插入成功返回1

END

ELSE

RETURN 0 — 插入失败返回0

END

存储过程中的获取方法

DECLARE @o_buyerid int

DECLARE @o_id bigint

DECLARE @result bit

EXEC @result = [nb_order_insert] @o_buyerid ,o_id bigint

3.SELECT 数据集返回值

CREATE PROCEDURE [dbo].[nb_order_select](

@o_id int

)

AS

BEGIN

SET NOCOUNT ON;

SELECT o_id,o_buyerid FROM [Order]

WHERE o_id = @o_id

GO

存储过程中的获取方法：

3.1使用临时表

CREATE TABLE [dbo].[Temp](

[o_id] [bigint] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,

[o_buyerid] [int] NOT NULL

)

INSERT [Temp] EXEC [nb_order_select] @o_id

– 这时 Temp 就是EXEC执行SELECT 后的结果集

SELECT * FROM [Temp]

DROP [Temp] — 删除临时表

3.2使用openrowset(不过就是速度不怎么样)

SELECT * from openrowset(’provider_name','Trusted_Connection=yes’,'exec nb_order_select’)
