1、查詢某個庫中所有的表名字
select [name] from sysobjects where xtype='u'and [name]<>'dtproperties' order by [name]
2、得到資料庫中所有使用者檢視
select [name] from sysobjects where xtype='v' and [name]<>'syssegments' and [name]<>'sysconstraints' order by [name]
3、獲得指定表中所有的列
select
c.name as columnname,
t.name as typename
from syscolumns c, systypes t, sysobjects o
where c.xtype = t.xusertype
and c.id = o.id
and o.name = 'book'
order by c.colorder
4、查詢庫中所有表的名字，以及表中資料的行數
select a.name, b.rows
from sysobjects as a inner join
sysindexes as b on a.id = b.id
where (a.type = 'u') and (b.indid in (0, 1))
order by b.rows desc
