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
