存储过程的三种返回值与其获得方法

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’)
