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

似乎你在编写查询时感到困惑，我希望以下查询可以帮助你

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

你正试图获得存储过程的输出值，如果你想消耗整个输出，下面就是这样。

下面的

是消耗整个sp输出的方法：

declare @test table
(id int)


create proc usp_test123
as
begin
select 1
end

insert into @test
exec usp_test123

select * from @test

否则，您可以使用输出返回和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

不确定您要做什么，但这是一种在程序中使用输出参数获取A / B等级然后打印它的方法：

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

如何在存储的prosedure中打印返回值？
