--查询其中一个数据库test,就可以得到这个数据库中的所有的表名了,语句如下:
USE test
go
select [id], [name] from [sysobjects] where [type] = ‘u‘ order by [name]
--查出v_lyb这个表中所有的字段
select [name] from [syscolumns] where [id] = 21575115 order by [colid]
--得到该表中的记录条数前提这个表中要建立索引
select [o].[id], [o].[name], [i].[rows] from [sysindexes] [i], [sysobjects] [o] where [i].[first]>0 and [o].[id]=[i].[id] and [o].[type]=‘u‘ and [o].[id]=21575115
