如何获取某一个表的所有字段？语句怎么写额！！

[tianyazaixian]

获取一个数据库里的所有表
use test
select table_name
from infomartion_schema.tables
where table_type='base table'
可以执行
获取一个表中的所有字段
select *
from syscolumns
where id=object_id('t')
可以执行
现在我想通过这两条语句一起查看为什么提示错误哈

select name from syscolumns
where id=object_id
('(select top 1 * from
(select table_name from information_schema.tables where
table_type='base table'))')

提示：服务器: 消息 170，级别 15，状态 1，行 13
第 13 行: 't' 附近有语法错误。
谢谢哈

select name from syscolumns 
where id=object_id
('(select top 1 * from (select table_name from information_schema.tables where table_type="base table") a)')

select name from syscolumns where id=object_id('表名')

[chuanzhang5687]

exec   sp_columns   'table_name '

楼主的提问标题与提问内容有差异.
如果想得到所有表的所有列:

select a.name as columnname,b.name as tablename from syscolumns a inner join sysobjects b on a.id=b.id and b.xtype='U'

[-晴天]

如果要获取指定表名的所有列,只需要:

select name from syscolumns 
where id=object_id('t')

为什么要再加上另一条语句呢?

按您的逻辑

select OBJECT_NAME(id) 表名,name 列名
from syscolumns
where id > 100 
and OBJECT_NAME(id) ='t'

GO 

exec UspOutputData 你的表名

[勿勿]

select name from syscolumns where .....

想要什么自己加进去。。

可能是我没有说明白，我现在是想通过语句获得这个‘T’（不是我指定的），谢谢。。。

你这个ID是怎么来的，可以告知一下吗？我是想通过语句获得T
