计算表空间的存储过程

我们公司的同事写的
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
