如何获取SQL Server数据库里表的占用容量大小

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
