我常用sp_spaceused来查看表所占的空间大小，可是一次只能看一个对象的。
今天有空写了个sp_spaceused2，可以同时看全部表的空间大小。
use master
go
EXEC sp_addmessage @msgnum = 55000, @severity = 16,
@msgtext = N'Objects of type %s do not have space allocated.',
@lang = 'us_english',@replace = 'replace'
EXEC sp_addmessage @msgnum = 55000, @severity = 16,
@msgtext = N'没有为类型 %1! 的对象分配的空间。',
@lang = '简体中文',@replace = 'replace'
go
if exists (select 1 from sysobjects where name = 'sp_spaceused2' and type = 'P')
drop procedure sp_spaceused2
go
create procedure sp_spaceused2 (
@type varchar(2) = 'U', -- The objects type we want size on.
@updateusage varchar(5) = false -- Param. for specifying that
-- usage info. should be updated.
)
