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"
