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 = @@IDENTITY
12 END
13 END
存储过程中获得方法：
1 DECLARE @age int
2 DECLARE @id bigint
3 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 BEGIN
10 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 int
2 DECLARE @id bigint
3 DECLARE @result bit
4 EXEC @result = [upInformation] @age ,id output
3.Select数据集返回值
1 CREATE PROCEDURE [dbo].[upInformation](
2 @id int
3 )
4 AS
5 BEGIN
6 SET NOCOUNT ON;
7 SELECT id,age FROM [Information]
8 WHERE id = @id
9 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 NULL
4 )
5 INSERT [Temp] EXEC [nb_order_select] @id
6 – 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
declare @table1 table(
[id] [bigint] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[age] [int] NOT NULL
)
INSERT into @table1 EXEC [nb_order_select] @id
