遍历数据表名、字段名、视图名甚至存储过程名

1、查询数据库中所有的用户表：

select [name] from sysobjects where xtype='u'
select * from information_schema.tables

2、查询某表[tableName]中所有的字段名称：

select [name] from syscolumns where id = object_id('[tableName]')
select * from information_schema.columns where TABLE_NAME='[tableName]'

3、查询所有视图信息：

select [name] from sysobjects where xtype='v'
select * from information_schema.views
