T-SQL 無參數的存儲過程的創建和執行

use StudentManager
go
if exists(select * from sysobjects where name='usp_ScoreQuery')
drop procedure usp_ScoreQuery
go
create procedure usp_ScoreQuery --創建存儲過程
as
    --查詢考試信息
    select Students.StudentId,StudentName,ClassName,
              ScoreSum=(CSharp+SQLServerDB) from Students
    inner join StudentClass on StudentClass.ClassId=Students.ClassId
    inner join ScoreList on Students.StudentId=ScoreList.StudentId
    order by ScoreSum DESC
    --統計分析考試信息
    select StudentClass.ClassId,C#Avg=avg(CSharp),DBAvg=avg(SQLServerDB)  into #scoreTemp
    from StudentClass 
    inner join Students on StudentClass.ClassId=Students.ClassId
    inner join ScoreList on ScoreList.StudentId=Students.StudentId
    group by StudentClass.ClassId order by ClassId
    select ClassName,C#Avg,DBAvg from #scoreTemp
    inner join StudentClass on StudentClass.ClassId=#scoreTemp.ClassId
go
exec usp_ScoreQuery  --調用存儲過程

這里的  into #scoreTemp  是把查詢的數據放入到臨時表中
