帶輸出引數的過程

use StuManageDB
go 
if exists(select * from sysobjects where name='usp_ScoreQuery3')
drop procedure usp_ScoreQuery3
go
create procedure usp_ScoreQuery3
@AbsentCount int output,
@FailedCount int output,
@CSharp int=60,
@DB int=60
as
    select Students.StudentId,StudentName,CSharp,SQLServerDB
    from
 
 Students
    inner join ScoreList on Students.StudentId=Students.StudentId
    where CSharp<@CSharp or SQLServerDb<@DB
    --查詢缺考人數
    select @AbsentCount=Count(*) from Students
    where StudentId not in(select StudentId from ScoreList)
    --查詢不及格人數
    select @FailedCount=Count(*) from ScoreList
    where
 
 CSharp<@CSharp or SQLServerDB<@DB

go

declare @AbsenCount int,@FailedCount int --定義輸出引數
exec usp_ScoreQuery3 @AbsenCount output,@FailedCount output
select 缺考總數[email protected],不及格總數[email protected]
