查看指定数据库中各个数据表大小

放在空间里，免得忘记，或许对其它人也有用

-------------------------------------------------------------------------------------------------------

Code
--  作用：查看当前数据库，各个数据表所占用的空间大小 
--1. 判断结果存储表是否存在，如果不存在，则创建，该表主要用于保存结果； 
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) ) 
--2. 求出当前数据库各个数据表大小，插入到结果表中； 
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 
--3. 显示结果 
select * from tablespaceinfo order by rowsinfo desc
