查询表空间使用率:

SELECT UPPER(F.TABLESPACE_NAME) "表空间名",
  D.TOT_GROOTTE_MB "表空间大小(M)",
  D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(M)",
  TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) / D.TOT_GROOTTE_MB * 100,2),‘990.99‘) || ‘%‘ "使用比",
  F.TOTAL_BYTES "空闲空间(M)",
  F.MAX_BYTES "最大块(M)"
  FROM (SELECT TABLESPACE_NAME,
  ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,
  ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES
  FROM SYS.DBA_FREE_SPACE
  GROUP BY TABLESPACE_NAME) F,
  (SELECT DD.TABLESPACE_NAME,
   ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB
  FROM SYS.DBA_DATA_FILES DD
  GROUP BY DD.TABLESPACE_NAME) D
