一、定义存储过程

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
 
 

二、执行存储过程
exec get_tableinfo

三、查询表数据

select *
from tablespaceinfo 
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc

************************************************************************************

简单分析：

1、单个表
EXEC sp_spaceused N'表名';

2、数据库
use [要查看的数据库]
sp_spaceused

3、所有数据库

exec sp_MSForEachDb @Command1 = "use ? exec sp_Spaceused"
