T-SQL 带参数存储过程

创建带参数的存储过程

 1 use StudentManager
 2 go
 3 if exists(select * from sysobjects where name=‘usp_ScoreQuery4‘)
 4 drop procedure usp_ScoreQuery4
 5 go
 6 create procedure usp_ScoreQuery4 --创建带参数的存储过程
 7 @AbsentCount int output,--缺考总人数
 8 @FailedCount int output,--不及格总人数
 9 @CSharp int=60,
10 @DB int=60
11 as
12     select Students.StudentId,StudentName,C#=CSharp,DB=SQLServerDB
13                  from Students
14                  inner join ScoreList on Students.StudentId=ScoreList.StudentId
15                  where CSharp<@CSharp or SQLServerDB<@DB        --显示结果列表
16     select @AbsentCount=count(*) from Students
17                 where StudentId not in(select StudentId from ScoreList) --查询缺考总人数
18     select @FailedCount=count(*) from ScoreList
19                  where CSharp<@CSharp or SQLServerDB<@DB      --查询不及格总人数
20 go

调用

1 use StudentManager
2 go
3 --调用带参数的存储过程
4 declare @AbsentCount int,@FailedCount int --首先定义输出参数
5 exec usp_ScoreQuery4 @AbsentCount output,@FailedCount output
6 --使用反馈的结果
7 select 缺考总数=@AbsentCount,不及格总数=@FailedCount

调用时传入输入参数

1 use StudentManager
2 go
3 --调用带参数的存储过程
4 declare @AbsentCount int,@FailedCount int --首先定义输出参数
5 exec usp_ScoreQuery4 @AbsentCount output,@FailedCount output ,65,70
6 --使用反馈的结果
7 select 缺考总数=@AbsentCount,不及格总数=@FailedCount
