使用spool输出csv格式查看系统表空间使用情况

SET ECHO OFF

SET TRIMOUT OFF

set feedback off

set heading on

set colsep ,

set trimspool on

set headsep off

set numw 10

set linesize 200

set pagesize 10000

col tablespace_name format a15

col total_space format a10

col free_space format a10

col used_space format a10

col used_rate format 99.99

spool /home/oracle/test.csv

select a.tablespace_name,a.total_space_Mb||‘m‘ total_space,b.free_space_Mb||‘m‘

free_space,a.total_space_Mb-b.free_space_Mb||‘m‘ used_space,

(1-(b.free_space_Mb/a.total_space_Mb))*100 used_rate,a.total_blocks,b.free_blocks from

(select tablespace_name,sum(bytes)/1024/1024 total_space_Mb,sum(blocks) total_blocks from dba_data_files

group by tablespace_name) a,

(select tablespace_name, sum((bytes)/1024/1024) free_space_Mb,sum(blocks) free_blocks from dba_free_space

group by tablespace_name) b

where a.tablespace_name=b.tablespace_name order by used_rate desc;

spool off

注（SET ECHO OFF不显示终端输入的start、@、@@等执行脚本命令、SET TERMOUT OFF在spool的时候结果不在终端显示、SET TRIMOUT OFF删除尾部空格）

结果如下：
