T-SQL 有參數存儲過程的創建與執行

use StudentManager
go
if exists(select * from sysobjects where name='usp_ScoreQuery2')
drop procedure usp_ScoreQuery2
go
--創建帶參數的存儲過程
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
--調用帶參數的存儲過程
exec usp_ScoreQuery2 60,65 --按照參數順序賦值
exec usp_ScoreQuery2 @DB=65,@CSharp=60 --參數順序可以調換

為參數賦默認值

use StudentManager
go
if exists(select * from sysobjects where name='usp_ScoreQuery3')
drop procedure usp_ScoreQuery3
go
--創建帶參數的存儲過程
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
--調用帶參數的存儲過程
exec usp_ScoreQuery3 65 --第二個參數沒有賦值，則默認
exec usp_ScoreQuery3 @DB=65
exec usp_ScoreQuery3 default,65 --不使用顯示方式賦值
exec usp_ScoreQuery3   --兩個參數都是用默認參數
