T-SQL 有参数存储过程的创建与执行

 use StudentManager
 go
 if exists(select * from sysobjects where name='usp_ScoreQuery2')
 drop procedure usp_ScoreQuery2
 go
 --创建带参数的存储过程
 create procedure usp_ScoreQuery2
 @CSharp int,
 @DB int
 as
     select Students.StudentId,StudentName,C#=CSharp,DB=SQLServerDB
     from Students
     inner join ScoreList on Students.StudentId=ScoreList.StudentId
     where CSharp<@CSharp or SQLServerDB<@DB
 go
 --调用带参数的存储过程
 exec usp_ScoreQuery2 60,65 --按照参数顺序赋值
 exec usp_ScoreQuery2 @DB=65,@CSharp=60 --参数顺序可以调换

为参数赋默认值

 use StudentManager
 go
 if exists(select * from sysobjects where name='usp_ScoreQuery3')
 drop procedure usp_ScoreQuery3
 go
 --创建带参数的存储过程
 create procedure usp_ScoreQuery3
 @CSharp int=60,
 @DB int=60
 as
     select Students.StudentId,StudentName,C#=CSharp,DB=SQLServerDB
     from Students
     inner join ScoreList on Students.StudentId=ScoreList.StudentId
     where CSharp<@CSharp or SQLServerDB<@DB
 go
 --调用带参数的存储过程
 exec usp_ScoreQuery3 65 --第二个参数没有赋值，则默认
 exec usp_ScoreQuery3 @DB=65
 exec usp_ScoreQuery3 default,65 --不使用显示方式赋值
 exec usp_ScoreQuery3   --两个参数都是用默认参数
