查找SQL数据表或视图中的字段属性信息

一、只支持表，非常牛逼的

SELECT a.name,(case when (SELECT count(*) FROM sysobjects WHERE (name in (SELECT name FROM sysindexes WHERE (id = a.id) AND
(indid in (SELECT indid FROM sysindexkeys WHERE (id = a.id) AND
(colid in (SELECT colid FROM syscolumns WHERE (id = a.id) AND (name = a.name))))))) AND (xtype = ‘PK‘))>0 then ‘1‘ else ‘0‘ end) isprimary,
b.name [type],COLUMNPROPERTY(a.id,a.name,‘PRECISION‘) as [length],isnull(g.value,‘‘) as [description]
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 sys.extended_properties g on a.id=g.major_id AND a.colid = g.minor_id
where  d.name =‘表明‘
order by a.id,a.colorder

二，一般牛逼，支持表

select object_name(id) as 表名 ,c.name as 字段名 ,t.name 数据类型 ,c.prec as 长度
from syscolumns c inner join systypes t on c.xusertype=t.xusertype
where objectproperty(c.id,‘IsUserTable‘)=1 and c.id=object_id(‘表明‘)

三、一般牛逼，支持视图

select object_name(id) as 表名 ,c.name as 字段名 ,t.name 数据类型 ,c.prec as 长度
from syscolumns c inner join systypes t on c.xusertype=t.xusertype
where objectproperty(c.id,‘IsView‘)=1 and c.id=object_id(‘V_ALLSay‘) 

求大神非常牛逼的，既支持表也支持视图的sql
