如何在存儲的打印中打印返回值？

Question

ALTER Procedure  [dbo].[sp1] 
@ID int 
As 
IF(SELECT Grade FROM Tb1 WHERE ID=@ID)BETWEEN 15 AND 20 
RETURN 'A' 
else 
RETURN 'B' 



Declare @ID1 int 
EXEC @ID1= sp1 '3'; 
Print convert(varchar(10) , @ID) 
Go 

Answer 1

好像你有以書面查詢迷茫，我希望下面的查詢可以幫助您

ALTER PROCEDURE [dbo].[sp1] 
@ID int 
As 
BEGIN 
SELECT CASE WHEN MARKS BETWEEN 15 AND 20 THEN 
'A' 
ELSE 
'B' 
END AS 'GRADE' 
FROM [TABLE] WHERE ID=@ID 
END 

Answer 2

您正試圖獲得存儲過程的輸出值，如果你想消費整個輸出，下面是辦法。

下面

是消耗整個SP輸出方式：

declare @test table 
(id int) 


create proc usp_test123 
as 
begin 
select 1 
end 

insert into @test 
exec usp_test123 

select * from @test 

否則，您可以使用輸出返回，並conusme特定值

create proc usp_test1234 
(
@id int out 
) 
as 
begin 
select @id=1 
end 

declare @id int 
exec usp_test1234 
@id =@id output 
select @id 

Answer 3

不知道你想做什麼，但這裏有一種方法可以在程序中用輸出參數獲取A/B等級，然後打印：

ALTER Procedure [dbo].[sp1] 
@ID int, 
@Grade char(1) output 
As 
IF (exists (SELECT 1 FROM Tb1 WHERE ID=@ID and Grade BETWEEN 15 AND 20)) 
set @Grade = 'A' 
else 
set @Grade = 'B' 
go 


Declare @ID1 int, @Grade char(1) 
set @ID1 = 3 
EXEC sp1 @ID1, @Grade output 
Print @Grade
