列出某数据库下的所有表
select table_name from information_schema.tables where table_type = 'base table'
或者
select object_name (id) from sysobjects where xtype = 'u' and objectproperty (id, 'ismsshipped') = 0
或者
使用sqlserver的存储过程“sp_tables”
adox是ado extensions for ddl and security，是微软对ado技术的扩展，使用它我们可以操作数据库的结构。它是一个com组件，估计以后在ado.net中会增加adox的一些功能。如果大家需要adox的一些资料，我可以提供。下面的一个例子就是使用adox来获得当前数据库的所有表。
摘抄
1.获取所有数据库名:
select name from master..sysdatabases order by name
2.获取所有表名:
select name from databasename..sysobjects where xtype='u' order by name
xtype='u':表示所有用户表;
xtype='s':表示所有系统表;
3.获取所有字段名:
select name from syscolumns where id=object_id('tablename')
access :
如果表存在，如何得到这个表？
select * from msysobjects where name='examresulttime ' and type=1 and flags=0
//得到该数据库中所有的表名
select name from msysobjects where type=1 and flags=0
1、获取所有用户名: select name from sysusers where status='2' and islogin='1' islogin='1' :表示帐户 islogin='0' :表示角色 status='2' :表示用户帐户 status='0' :表示糸统帐户 2、获取所有数据库名: select name from master..sysdatabases order by name 3、获取所有表名: select name from databasename..sysobjects where xtype='u' order by name xtype='u' :表示所有用户表; xtype='s' :表示所有系统表; 4、获取所有字段名: select name from syscolumns where id=object_id('表名'') 5、获取数据库所有类型: select name from systypes 6、获取主键字段: select name from syscolumns where id=object_id('表名') and colid=(select top 1 keyno from sysindexkeys where id=object_id('表名')) 7、获取表字段的基本信息: 程序代码 select 字段名=rtrim(b.name), 主键=case when h.id is not null then 'pk' else '' end, 字段类型=type_name(b.xusertype)+case when b.colstat&1=1 then '[id(' + convert(varchar, ident_seed(a.name))+','+convert(varchar,ident_incr(a.name))+')]' else '' end, 长度=b.length, 允许空=case b.isnullable when 0 then 'n' else 'y' end, 默认值=isnull(e.text, ''), 字段说明=isnull(c.value, '') from sysobjects a, syscolumns b left outer join sysproperties c on b.id = c.id and b.colid = c.smallid left outer join syscomments e on b.cdefault = e.id left outer join (select g.id, g.colid from sysindexes f, sysindexkeys g where (f.id=g.id)and(f.indid=g.indid)and(f.indid>0)and(f.indidand(f.status&2048)0) h on (b.id=h.id)and(b.colid=h.colid) where (a.id=b.id)and(a.id=object_id('要查询的表')) --要查询的表改成你要查询表的名称 order by b.colid 程序代码 select 表名=case when a.colorder=1 then d.name else '' end, 表说明=case when a.colorder=1 then isnull(f.value,'') else '' end, 字段序号=a.colorder, 字段名=a.name, 标识=case when columnproperty(a.id,a.name,'isidentity')=1 then '√' else '' end, 主键=case when exists(select 1 from sysobjects where xtype='pk' and name in (select name from sysindexes where indid in(select indid from sysindexkeys where id=a.id and colid=a.colid))) then '√' else '' end, 类型=b.name, 字段长度=a.length, 占用字节数=columnproperty(a.id,a.name,'precision'), 小数位数=isnull(columnproperty(a.id,a.name,'scale'),0), 允许空=case when a.isnullable=1 then '√'else '' end, 默认值=isnull(e.text,''), 字段说明=isnull(g.[value],'') from syscolumns a left join systypes b on a.xusertype=b.xusertype inner join sysobjects d on (a.id=d.id)and(d.xtype='u')and(d.name'dtproperties') left join syscomments e on a.cdefault=e.id left join sysproperties g on (a.id=g.id)and(a.colid=g.smallid) left join sysproperties f on (d.id=f.id)and(f.smallid=0) --where d.name='要查询的表' --如果只查询指定表,加上此条件 order by a.id,a.colorder
