查看SQL Server数据空间分配情况

   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

备注：
Namenvarchar(20)为其请求空间使用信息的表名。Rowschar(11)表中现有的行数。reservedvarchar(18)表保留的空间总量。Datavarchar(18)表中的数据所使用的空间量。index_sizevarchar(18)表中的索引所使用的空间量。Unusedvarchar(18)表中未用的空间量。
