1. 查詢表空間剩余字節大小SELECT TABLESPACE_NAME, SUM(BYTES)/1024/1024 AS "FREE SPACE(M)"

FROM DBA_FREE_SPACE

WHERE TABLESPACE_NAME = '&tablespace_name'

GROUP BY TABLESPACE_NAME;注：如果是臨時表空間，請查詢DBA_TEMP_FREE_SPACESELECT TABLESPACE_NAME, FREE_SPACE/1024/1024 AS "FREE SPACE(M)"

FROM DBA_TEMP_FREE_SPACE

WHERE TABLESPACE_NAME = '&tablespace_name';
