select distinct
sysobjects.[name] as tablename,
syscolumns.[name] as columnname ,
cast(sysproperties.value as varchar(100)) as [descript]
From
sysobjects,syscolumns ,sysproperties
where
sysobjects.id = syscolumns.id and
sysproperties.id=sysobjects.id and
sysproperties.smallid = syscolumns.colid


or

SELECT *
FROM ::fn_listextendedproperty ('MS_Description', 'user', 'dbo', 'table', 'tablename', 'columnname', default)

我一般用这个视图
Create view fielddesc
as
select o.name as oname, c.name as cname,convert(varchar(30),p.value) as value,p.smallid as psmallid,t.name as tname
from syscolumns c
join systypes t on c.xtype = t.xtype
join sysobjects o on o.id=c.id
left join sysproperties p on p.smallid=c.colid and p.id=o.id
where o.xtype='U'

--
Select * from fielddesc where oname = 'yourTable'
