SQL Server
  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
