查询以列出Oracle表空间

如何通过显示来列出Oracle所有表空间+临时表空间

通过一个SQL查询分配空间（MB）、已用空间（MB）、状态（联机/脱机）和键入

SQL> set pagesize 100
SQL> set linesize 100
SQL> break on tablespace_name on status on total_mb
SQL> compute sum of used_mb on tablespace_name
SQL> WITH total
  2       AS (  SELECT f.tablespace_name,
  3                    ROUND (SUM (f.bytes) / POWER (2, 20)) total_mb
  4               FROM dba_data_files f
  5           GROUP BY f.tablespace_name),
  6       used
