如何擷取SQL Server資料庫裡表的佔用容量大小的預存程序

其實只要使用系統內建的預存程序sp_spaceused就可以得到表的相關資訊

如：sp_spaceused 'tablename'

以下是為了方便寫的一個預存程序，目的是把當前的所有表的相關資訊全部都儲存在一個指定的表裡面

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                         --建立結果儲存表
              (nameinfo varchar(50) , 
               rowsinfo int , reserved varchar(20) , 
               datainfo varchar(20)  , 
               index_size varchar(20) , 
               unused varchar(20) )
 
 
delete from tablespaceinfo --清空資料表
 
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
 
 

執行預存程序
exec get_tableinfo

查詢運行該預存程序後得到的結果
select *
from tablespaceinfo 
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc
