CREATE PROCEDURE get_tableinfo AS

create table  tablespaceinfo                         --创建结果存储表

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
