T-SQL 视图

 use StudentManager
 go
 --判断视图是否存在
 if exists(select * from sysobjects where name='view_ScoreQuery')
 drop view view_ScoreQuery
 go
 --创建视图
 create view view_ScoreQuery
 as
     select top 1000 Students.StudentId,StudentName,ClassName,
              C#=CSharp,SQLDB=SQLServerDB,
              ScoreSum=(CSharp+SQLServerDB) from Students
              inner join ScoreList on Students.StudentId=ScoreList.StudentId
              inner join StudentClass on Students.ClassId=StudentClass.ClassId
              order by StudentClass.ClassId
 go
 --使用视图查询
 select * from view_ScoreQuery

视图里面如果想用order by 排序,必须要加入top,所以视图里不建议加order by ,想要加order by 建议在调用视图的时候加
