1、sys.all_objects(系统视图)数据库中所有的对象，包含了创建时间和最近修改时间。

--查找存储过程
--所有的存储过程
select * from sys.all_objects where type='P' order by modify_date desc
--2009年3月5号后新建的存储过程
select * from sys.all_objects where type='P' and create_date>'2009-3-5' order by name
--3月5号前建的3月5号后修改过的
select * from sys.all_objects where type='P' and modify_date>'2009-3-5' and create_date<'2009-3-5' order by name

2、sys.objects、sysobjects、syscolumns、systypes....

不想写了保存一个SQL吧。查找数据库信息的sql查出所有用户表的所有字段。
