总结了几个常用的sql server系统表的使用

--查看表的属性select * from sysObjects where [Name] = 'section' --用法 if exists ( select * from sysObjects where [Name] = 'section'  and xtype='U' )     Drop Table table1   go Create table1 ( )

--获取所有用户表select Name from sysobjects where xtype='u' and status>=0

--查看表的字段select * from  sysColumns c where c.id=object_id('section')select name from syscolumns where id=object_id('表名') --查看用户select * From  sysusers where status<>0

--查看谁引用了bbs_hits表（包括视图、存储过程、函数）Select distinct object_name(d.id) as 'program',        o.xtype   from sysdepends d inner join sysobjects o on d.id=o.id   where object_name(depid)='bbs_hits'

--查看与某一个表相关的视图、存储过程、函数  select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'

--查看当前数据库中所有存储过程select name as 存储过程名称 from sysobjects where xtype='P'

--查询某一个表的字段和数据类型select column_name,data_type from information_schema.columnswhere table_name = '表名' [n].[标题]:Select * From TableName Order By CustomerName

其中xtype分别对应：

C = CHECK 约束 D = 默认值或 DEFAULT 约束 F = FOREIGN KEY 约束 FN = 标量函数 IF = 内嵌表函数 K = PRIMARY KEY 或 UNIQUE 约束 L = 日志 P = 存储过程 R = 规则 RF = 复制筛选存储过程 S = 系统表 TF = 表函数 TR = 触发器 U = 用户表 V = 视图 X = 扩展存储过程
