如何获取SQL Server数据库里表的占用容量大小?

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'

step 1：先写一个存储过程，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

step 2：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
