t_class.sql

基于C#语言的一个教务网数据库系统开发案例的源代码 ,很实用哦

if exists (select 1
            from  sysobjects
           where  id = object_id('class')
            and   type = 'U')
   drop table class
go
/*==============================================================*/
/* Table: 班级                                                    */
/*==============================================================*/
create table class (
Class_id             varchar(50)          not null,
