sql下master数据库分析，了解下master数据库主要是做什么用的
表sysdatabases：保存DBMS中数据库信息select [name] from [sysdatabases] order by [name]
就能得到该DBMS中的数据库信息
表sysobjects：保存数据库中数据表信息
con.ChangeDatabase(DBName)
select [id],[name] from [sysobjects] where [type]='u',con
就能得到该数据库的表信息
表syscolumns：保存数据表的列信息
select [name] from [syscolumns] where [id]="从sysobjects中获取该表的id"
就能得到该表的列信息
