其实只要使用系统内置的存储过程sp_spaceused就可以得到表的相关信息

如：sp_spaceused 'tablename'


以下是为了方便写的一个存储过程，目的是把当前的所有表的相关信息全部都保存在一个指定的表里面

CREATE PROCEDURE get_tableinfo AS

if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[tablespaceinfo]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
create table  tablespaceinfo                         --创建结果存储表
              (nameinfo varchar(50) ,  
               rowsinfo int , reserved varchar(20) ,  
               datainfo varchar(20)  ,  
               index_size varchar(20) ,  
               unused varchar(20) )


delete from tablespaceinfo --清空数据表

declare @tablename varchar(255)  --表名称

declare @cmdsql varchar(500)

DECLARE Info_cursor CURSOR FOR  
select o.name   
from dbo.sysobjects o where OBJECTPROPERTY(o.id, N'IsTable') = 1  
     and o.name not like N'#%%'  order by o.name

OPEN Info_cursor

FETCH NEXT FROM Info_cursor  
INTO @tablename  

WHILE @@FETCH_STATUS = 0
BEGIN

  if exists (select * from dbo.sysobjects where id = object_id(@tablename) and OBJECTPROPERTY(id, N'IsUserTable') = 1)
  execute sp_executesql  
         N'insert into tablespaceinfo  exec sp_spaceused @tbname',
          N'@tbname varchar(255)',
          @tbname = @tablename

  FETCH NEXT FROM Info_cursor  
  INTO @tablename  
END

CLOSE Info_cursor
DEALLOCATE Info_cursor
GO



执行存储过程
exec get_tableinfo

查询运行该存储过程后得到的结果
select *
from tablespaceinfo  
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc
