Question

如何通过显示

列出Oracle 所有表空间+ temp表空间

使用一个SQL查询分配空间（MB），已用空间（MB），状态（在线\离线）和类型？

Answer 1

像这样吗？

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
  7       AS (  SELECT s.tablespace_name,
  8                    s.segment_type,
  9                    ROUND (SUM (s.bytes) / POWER (2, 20)) used_mb
 10               FROM dba_segments s
 11           GROUP BY s.tablespace_name, s.segment_type)
 12    SELECT ts.tablespace_name,
 13           ts.status,
 14           t.total_mb,
 15           u.segment_type,
 16           u.used_mb
 17      FROM dba_tablespaces ts
 18           JOIN total t ON t.tablespace_name = ts.tablespace_name
 19           JOIN used u ON u.tablespace_name = ts.tablespace_name
 20  ORDER BY ts.tablespace_name, u.segment_type;
