使用SQL语句获取SQL Server数据库表中某字段的信息（字段名、字段说明、默认值等）

select 
object_name(c.id) as 表名
 ,c.name as 字段名
 ,t.name as 数据类型
 ,c.prec as 长度
 ,p.value as 字段说明
 ,m.text as 默认值
from syscolumns c
 inner join
 systypes t
 on c.xusertype=t.xusertype
 left join 
 sys.extended_properties p
 on c.id=p.major_id and c.colid = p.minor_id
 left join
 syscomments m
 on c.cdefault=m.id
where objectproperty(c.id,'IsUserTable')=1
 and object_name(c.id) = 'Article' and c.name = 'Hits' --本行中的"Article"为表名,"Hits"为字段名

　　在SQL Server 2008中测试通过，运行截图：
