今天客戶反映數據庫文件空間增長過快，需要分析數據庫表存放空間分配情況，臨時寫了以下過程，

與大家共享。

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) ,

               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

--knowsky.com數據庫信息
sp_spaceused @updateusage = 'true'

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