如何取得一个数据表的所有列名
方法如下：先从SYSTEMOBJECT系统表中取得数据表的SYSTEMID,然后再SYSCOLUMN表中取得该数据表的所有列名。SQL语句如下：
declare @objid int,@objname char(40)
set @objname = 'tablename'
select @objid = id from sysobjects where id = object_id(@objname)
select 'Column_name' = name from syscolumns where id = @objid order by colid
自己修改如下，可以直接放到程序中执行
SELECT name
FROM syscolumns
WHERE (id =
(SELECT id
FROM sysobjects
WHERE (id = OBJECT_ID('YOURTABLENAME'))))
ORDER BY colid
