isnull(g.[value],'') AS N'字段说明'
FROM syscolumns a left join systypes b
on a.xtype=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 
order by object_name(a.id),a.colorder

可以将以上代码放到SQL查询分析器上运行一下就知道了(当然要打开一个数据库啦)
