1.output引數返回值

1


create procedure [dbo].[upinformation](


2 @age int,3


@id bigint output4)


5as6begin


7set nocount on;


8begin


9insert into [information](age )


10values (@age )


11set @id = @@identity


12end


13 end
儲存過程中獲得方法：

1 declare @age int


2declare @id bigint


3 exec [upinformation] @age,@id output
2.return過程返回值

1


create procedure [dbo].[upinformation](


2 @age int,3


@id bigint output4)


5as6begin


7set nocount on;


8 if(exists(select * from [shop] where [s_id] =@age ))


9begin


10insert into [information](age ) values (@age ) 


11set @id =


@@identity


12return 1 — 插入成功返回1 


13end 


14else 


15return 0


— 插入失敗返回0


16 end
儲存過程中獲得方法：

1 declare @age int


2declare @id bigint


3declare @result bit


4 exec @result = [upinformation] @age ,id output
3.select資料集返回值

1


create procedure [dbo].[upinformation](


2 @id int3)


4as5begin


6set nocount on;


7select id,age from [information]


8 where id = @id


9 go
儲存過程中獲得方法：(使用臨時表)

1


create table [dbo].[temp](


2 [id] [bigint] identity(1,1


) not for replication not null,


3 [age] [int


] not null4)


5insert [temp] exec [nb_order_select] @id


6– 這時 temp 就是exec執行select 後的結果集


7 select *from [temp]


8 drop [temp] — 刪除臨時表
c#獲取return返回值

1 sqlconnection conn = new sqlconnection(configurationmanager.connectionstrings["


connstr


"].tostring());


2conn.open();


3 sqlcommand mycommand = new sqlcommand("


upinformation


", conn);  //


儲存過程名字


4 mycommand.commandtype = commandtype.storedprocedure;　　　//


指定型別為儲存過程


5 mycommand.parameters.add(new sqlparameter("@a"


, sqldbtype.int));


6 mycommand.parameters["


@a"].value = 10


;7 mycommand.parameters.add(new sqlparameter("@b"


, sqldbtype.int));


8 mycommand.parameters["


@b"].value = 20


;9 mycommand.parameters.add(new sqlparameter("


@return


", sqldbtype.int));


10 mycommand.parameters["


@return


"].direction =parameterdirection.returnvalue;


11 mycommand.executenonquery();                //


執行儲存過程


12 response.write(mycommand.parameters["


@return


"].value.tostring()); //


取得return的返回值
c#獲取output輸出引數值

1 sqlconnection conn = new sqlconnection(configurationmanager.connectionstrings["


connstr


"].tostring());


2conn.open();


3 sqlcommand mycommand = new sqlcommand("


upinformation


", conn);


4 mycommand.commandtype =commandtype.storedprocedure;


5 mycommand.parameters.add(new sqlparameter("@a"


, sqldbtype.int));


6 mycommand.parameters["


@a"].value = 20


;7 mycommand.parameters.add(new sqlparameter("@b"


, sqldbtype.int));


8 mycommand.parameters["


@b"].value = 20


;9 mycommand.parameters.add(new sqlparameter("@c"


, sqldbtype.int));


10 mycommand.parameters["


@c"].direction =parameterdirection.output;


11mycommand.executenonquery();


12 response.write(mycommand.parameters["


@c"].value.tostring()); //


指定取得儲存過程的返回值
c#接收儲存過程返回值

c#取得結果集
