第一种方法(较简单，看的有些吃力)：

exec sp_MSforeachtable "exec sp_spaceused '?'"

第二种方法(较复杂，但看的比较清楚，原作者不详)：

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


--itlearner注：显示数据库信息
sp_spaceused @updateusage = 'TRUE' 

--itlearner注：显示表信息
select * 
from tablespaceinfo 
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc

第三种方法：

select object_name(id) tablename,8*reserved/1024 reserved,rtrim(8*dpages/1024)+'Mb' used,8*(reserved-dpages)/1024 unused,8*dpages/1024-rows/1024*minlen/1024 free,
rows,* from sysindexes 
where indid=1 
order by reserved desc
