sql查询表空间的使用量、剩余量及其它情况

在网上看到这个Oracle的sql，由此想到SqlServer的对应sql是什么？一样吗？No，

错误：

消息 208，级别 16，状态 1，第 1 行
对象名 ’sm$ts_used’ 无效。

下边是原文：(http://oldwain.itpub.net/post/6/449417)

查询表空间的使用量、剩余量：

select * from sm$ts_used;
 
select * from sm$ts_free;

比起用其它的视图写长长的一段脚本， 简便多了。

两个视图的定义：

SQL>select text from dba_views where  view_name =   ’SM$TS_FREE’;
 
TEXT

--------------------------------------------------------------------------------

select tablespace_name, sum(bytes) bytes from dba_free_space

    group by tablespace_name
 
SQL>select text from dba_views where  view_name =   ’SM$TS_USED’;
TEXT

--------------------------------------------------------------------------------

select tablespace_name, sum(bytes) bytes from dba_segments

    group by tablespace_name

据说从7.x到11g都可以用。

经过查询，SqlServer的对应sql是：

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

运行代码：

--itlearner注：显示数据库信息
sp_spaceused @updateusage = ’TRUE’
--itlearner注：显示表信息
select *
from tablespaceinfo
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc

运行结果：
