如何獲取SQL Server數據庫里表的占用容量大小?


其實只要使用系統內置的存儲過程sp_spaceused就可以得到表的相關信息

如：sp_spaceused 'tablename'


step 1：先寫一個存儲過程，把當前的所有表的相關信息全部都保存在一個指定的表里面

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 --創建結果存儲表
(nameinfo varchar(50) ,
rowsinfo int , reserved varchar(20) ,
datainfo varchar(20) ,
index_size varchar(20) ,
unused varchar(20) )


delete from tablespaceinfo --清空數據表

declare @tablename varchar(255) --表名稱

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


step 2：執行存儲過程
exec get_tableinfo

查詢運行該存儲過程后得到的結果
select *
from tablespaceinfo
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc
