1.Output参数返回值

1 CREATE PROCEDURE [dbo].[upInformation]( 2 @age int , 3 @id bigint OUTPUT 4 ) 5 AS 6 BEGIN 7 SET NOCOUNT ON; 8 BEGIN 9 INSERT INTO [Information](age )10 VALUES (@age )11 SET @id = @@IDENTITY12 END13 END

存储过程中获得方法：

1 DECLARE @age int2 DECLARE @id bigint3 EXEC [upInformation] @age,@id output

 

2.Return过程返回值

1 CREATE PROCEDURE [dbo].[upInformation]( 2 @age int , 3 @id bigint OUTPUT 4 ) 5 AS 6 BEGIN 7 SET NOCOUNT ON; 8 IF(EXISTS(SELECT * FROM [Shop] WHERE [s_id] = @age )) 9 BEGIN10  INSERT INTO [Information](age ) VALUES (@age ) 11  SET @id = @@IDENTITY 12  RETURN 1 — 插入成功返回1 13 END 14 ELSE 15  RETURN 0 — 插入失败返回0 16 END

存储过程中获得方法：

1 DECLARE @age int2 DECLARE @id bigint3 DECLARE @result bit4 EXEC @result = [upInformation] @age ,id output

 

3.Select数据集返回值

1 CREATE PROCEDURE [dbo].[upInformation](2 @id int3 )4 AS5 BEGIN6 SET NOCOUNT ON;7 SELECT id,age FROM [Information]8 WHERE id = @id9 GO

存储过程中获得方法：(使用临时表)

1 CREATE TABLE [dbo].[Temp](2 [id] [bigint] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,3 [age] [int] NOT NULL4 )5 INSERT [Temp] EXEC [nb_order_select] @id6 – 这时 Temp 就是EXEC执行SELECT 后的结果集7 SELECT * FROM [Temp]8 DROP [Temp] — 删除临时表
