如何获取SQL Server数据库里表的占用容量大小

【 tulaoshi.com - SQLServer 】

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
