查看SQL Server数据空间分配情况

本文主要是介绍查看SQL Server数据空间分配情况，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

今天客户反映数据库文件空间增长过快 ，需要分析数据库表存放空间分配情况，临时写了以下过程，
与大家共享。

if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[tablespaceinfo]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
create table  tablespaceinfo                         --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

--knowsky.com数据库信息
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

1、查看当前库里面每个表空间的占用情况

select object_name(id) tablename,8*reserved/1024 reserved,rtrim(8*dpages/1024)+''Mb'' used,8*(reserved-dpages)/1024 unused,8*dpages/1024-rows/1024*minlen/1024 free,
rows,* from sysindexes
where indid=1
order by reserved desc

2、 查看单个表　exec sp_spaceused  表名称

查看多表可通过游标取出sysobjects表中xtype=''U''的表，取出表空间的情况

这篇关于查看SQL Server数据空间分配情况的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
