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.columns
where 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
