SQL Server 系统表简介 系统目录是由描述SQL Server 系统的数据库.基表.视图和索引等对象的结构的系统表组成.SQL Server 经常访问系统目录,检索系统正常运行所需的必要信息. 1. Sysobjects表 SQL Server 的主系统表sysobjects出现在每个数据库中,它对每个数据库对象含有一行记录. 2. Syscolumns表 系统表syscolumns出现在m
1.使用DELETE实现SQL Server删除表信息 (1)删除表中的全部信息 USE student GO DELETE student --不加where条件,删除表中的所有记录 go (2)删除表中符合条件的记录 USE student GO DELETE student where Id='001' --删除表中符合条件的记录 GO 2.使用TRUNCATE删除表中的信息 USE student GO TRUNCATE TABLE student --删除表中
