刚好需要这个过程, 在网上找了几个, 感觉都差一些, 其SQL都特别长. 而且我特别需要用到聚类索引, 自己写了个, 这是程序开发使用到的版本.
select o.name tablename, c.name fieldname, t.name fieldtype, columnproperty(c.id,c.name,'PRECISION') fieldlen, c.Scale,c.length,
c.colid fieldorder, c.isnullable,
case when c.colid in(select ik.colid
from sysindexes i, Sysindexkeys ik, sysobjects oo
where i.id=ik.id and i.indid=ik.indid
and i.name=oo.name and oo.xtype='PK' --主键
and o.id=i.id
) then 1 else 0 end isPrimaryKey,
case when c.colid in(select ik.colid
from sysindexes i, Sysindexkeys ik
where i.id=ik.id and i.indid=ik.indid
and o.id=i.id and i.indid=1 --聚类索引
) then 1 else 0 end isClusterKey,
columnproperty( c.id, c.name,'IsIdentity') IsIdentity,
isnull(m.text,'') defaultvalue
from sysobjects o, syscolumns c, systypes t, syscomments m
where o.xtype='U'
and o.id=c.id
and c.xtype=t.xtype
and c.cdefault*=m.id
order by o.name, c.colid

程序使用到的版本是否用0/1表示, 如果用在文档整理, 难看得要命, 优化了个文档版本的,在查询分析器找出来还是蛮好看的.
select case when c.colid=1 then o.name else '' end 表名,
c.colid 顺序,
c.name 字段名,
t.name 字段类型,
columnproperty(c.id,c.name,'PRECISION') 字段长度,
isnull(c.Scale,'') 小数位,
c.length 占用字节,
case when c.isnullable=1 then '√' else '' end 可为空,
case when c.colid in(select ik.colid
from sysindexes i, Sysindexkeys ik, sysobjects oo
where i.id=ik.id and i.indid=ik.indid
and i.name=oo.name and oo.xtype='PK' --主键
and o.id=i.id
) then '√' else '' end 主键,
case when c.colid in(select ik.colid
from sysindexes i, Sysindexkeys ik
where i.id=ik.id and i.indid=ik.indid
and o.id=i.id and i.indid=1 --聚类索引
) then '√' else '' end 聚类索引,
case when columnproperty( c.id, c.name,'IsIdentity')=1 then '√' else '' end 自增长,
isnull(m.text,'') 默认值
from sysobjects o, syscolumns c, systypes t, syscomments m
where o.xtype='U'
and o.id=c.id
and c.xtype=t.xtype
and c.cdefault*=m.id
order by o.name, c.colid
