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：

name

nvarchar(20)

为其请求空间使用信息的表名。

rows

char(11)

表中现有的行数。
